SUMMARY:CMB Seminar: Tatiana Segura
DESCRIPTION:Title: From soft microparticle assemblies to tissue scaffolds \nAbstract: Particle assemblies form interconnected pockets of empty space that are hot spots for activity in many applications and natural phenomenon that deal with particulate matter. In my lab we explore the use of interlinked soft microparticle assemblies as scaffolds for cell culture in vitro and to promote regenerative wound healing in vivo. The open space that is created by these soft microparticle assemblies can be engineered to guide cellular behavior through restricting the space occupied by cells by modulating particle size\, changing the chemical composition of the open space\, and activating the cells with soluble factors. Using these approaches\, we have studied the role of open space on macrophage polarization\, neuroprogenitor cell growth\, and vascular morphogenesis. Injection of these materials into wounds result in the local modulation of immune cells that turn the environment towards a reparative environment and leads to scarless healing skin. In this talk\, I will discuss our latest results in our creation of soft particle assemblies for biomedical applications. \nHost: Karen Daniels

SUMMARY:Physics Colloquium: Qiang Cui
DESCRIPTION:Qiang Cui\, Boston University \nTitle: Lipid Membrane Remodeling by Proteins and Peptides: Mechanistic insights from multi-scale analysis \nAbstract: We will discuss the analysis of membrane remodeling by proteins and peptides using multi-scale computational methods; these include mainly molecular dynamics simulations at atomistic and coarse-grained levels\, although we will also touch upon analyses using lattice models and a mean-field theory. The discussions will cover several systems that we have analyzed in recent studies\, which include the SAR1 protein from the COPII machinery and the ESCRTIII complex; we will also briefly discuss how protein condensates interact with lipid membranes\, especially in terms of their mutual influence on morphology and phase behaviors. These examples illustrate different molecular properties and mechanisms that are potentially relevant to membrane remodeling\, as well as the values and limitations of various computational methodologies in such context. \nHost: Xingcheng Lin

SUMMARY:Physics Colloquium: Geraldine Cochran
DESCRIPTION:Geraldine Cochran\, The Ohio State University  \nTitle: Rethinking What it Means to be Underprepared in Physics \nAbstract: Dominant narratives in introductory physics education often focus on student preparation in mathematics. Students who have not reached a certain level of proficiency as determined by math placement tests are often labeled as underprepared. In this presentation\, I will challenge this narrative by reframing the notion of underprepared. Indeed\, many physics departments and instructors are underprepared to support the students accepted into their institutions. The Transforming Introductory Physics Sequences to Support all Students (TIPSSS) Network is a network of physicists developing curricular materials\, transforming courses\, and research the effectiveness of these efforts to help departments meet the needs of their physics students\, regardless of the students’ prior mathematics preparation. I will present and overview of the TIPSSS activities and also preliminary findings from the TIPSSS studies. \nHost: Kasey Wagoner

SUMMARY:Physics Colloquium: Jonah Miller
DESCRIPTION:Jonah Miller\, Los Alamos National Lab \nTitle: What High Fidelity Supercomputer Simulations Can Teach Us About Matter at the Highest Densities and the Origin of Heavy Elements \nAbstract: The 2017 detection of the in-spiral and merger of two neutron stars was a landmark discovery in astrophysics. Through a wealth of multi-messenger data\, we now know that the merger of these ultracompact stellar remnants is a central engine of short gamma ray bursts and a site of r-process nucleosynthesis\, where the heaviest elements in our universe are formed. The radioactive decay of unstable heavy elements produced in such mergers powers an optical and infra-red transient: The kilonova.\nAlong with core-collapse supernovae\, neutron star mergers offer insight into the behavior of matter at incredibly high densities and temperatures. While pairwise interactions in this regime are well understood\, collective behavior is not. This is the so-called high-temperature nuclear equation of state\, and it is a grand challenge problem in nuclear physics.\nIn this talk\, I present my research program of nuclear astrophysics\, where I use high-fidelity supercomputer simulations to investigate both the origin of heavy elements and the nuclear equation of state in core collapse supernovae\, neutron star mergers\, and their aftermath. I will discuss exciting results in this area\, as well as recent progress on new modeling capabilities that leverage GPU computing. \nHost: Carla Fröhlich \n

SUMMARY:Physics Colloquium: Kim Venn
DESCRIPTION:Kim Venn\, University of Victoria \nTitle: Exploring the Faintest Milky Way Satellites \nAbstract: Star clusters and dwarf galaxies are known to cohabit the outer Milky Way halo\, occasionally as tidally disrupted streams. It is useful to distinguish these objects\, as the “ultra faint” dwarf galaxies probe the low mass end of the dark matter halo distribution function\, and their properties are used to constrain dark matter particle scenarios. Similarly\, any dispersions or wrinkles in tidally disrupted “star cluster” streams are used to explore the cold dark matter subhalo population in the Milky Way halo. Unfortunately\, the faintest of these systems\, where the physics becomes the most interesting\, are the most challenging to classify and do impact our understanding of dark matter. In this talk\, I will discuss faint stellar systems found in recent imaging surveys\, and the efforts to use chemistry\, dynamics\, and N-body simulations to reveal their underlying nature(s). \nHost: Ian Roederer

SUMMARY:CMB Seminar: Charles Maher
DESCRIPTION:Title: Hyperuniformity of Disordered Network Metamaterials Derived from Hyperuniform Point Patterns \nAbstract: Disordered hyperuniform two-phase heterogeneous materials are those whose density fluctuations are anomalously suppressed at large length scales compared to standard disordered materials. Such hyperuniform materials are found to possess unique and desirable transport and elastic properties that are isotropic and robust to defects. Disordered network metamaterials are another exciting class of structure\, which have better stiffness- and strength-to-weight ratios than their bulk counterparts. Thus\, it is of interest to design and characterize disordered hyperuniform network metamaterials that inherit the desirable properties of both of the aforementioned classes of media. Here\, we characterize the structure of networks generated via Voronoi\, Delaunay\, Delaunay-Centroidal\, and Gabriel tessellations of stealthy and non-stealthy hyperuniform point patterns with tunable short-range disorder. In particular\, we examine the extent to which the hyperuniformity of the underlying point pattern is preserved when converted into a disordered network metamaterial. This work will inform the design of 3D-printable disordered hyperuniform materials for use in\, e.g.\, the biomedical and areospace fields. \nHost: Karen Daniels \nZoom: https://ncsu.zoom.us/j/99432171491

SUMMARY:Physics Colloquium: Gleb Finkelstein
DESCRIPTION:Gleb Finkelstein\, Duke University \nTitle: Multiterminal Graphene-based Josephson Junctions — a Playground for Non-linear and Quantum Physics \nAbstract: Josephson junctions are at the heart of many quantum devices\, including superconducting qubits. In the recently developed multi-terminal Josephson junctions\, several superconducting contacts are made to a common non-superconducting region. It has been predicted that these devices could emulate the electronic bands of a real crystal\, including topological materials.\nIn this talk\, I introduce Josephson junctions and present the recent work on the multi-terminal junctions made of graphene. Our main interest is the “multiplet” resonances\, which are observed at commensurate voltages across the junctions. We show that these resonances can be established via a synchronization mechanism analogous to the classical dynamics of the Kapitza pendulum.\n \nHost: Weijian Chen

SUMMARY:CMB Seminar: Wilton Snead
DESCRIPTION:Title: Decoding Intracellular Organization by Biomolecular Condensation \nAbstract: The precise organization of biochemical functions in time and space is essential for cellular life. Intracellular organization is facilitated by the division of biomolecules into subcellular organelles. While classical organelles employ a lipid bilayer membrane to separate materials from the surrounding environment\, an emerging class of organelles called biomolecular condensates do not utilize a delimiting membrane. Rather\, multivalent interactions among proteins and nucleic acids drive the formation of concentrated\, dynamic assemblies. Condensates regulate diverse cellular processes from transcription to signaling\, and pathological condensates contribute to cancer and neurodegeneration. The physiological and pathological functions of condensates depend on key physical parameters such as size\, subcellular location\, and biomolecular composition. However\, the mechanisms that control condensate properties and prevent the mixing of functionally distinct condensates remain largely unclear. My work examines how fundamental geometric and physical constraints in cells are exploited to control condensate form and function. In particular\, I examine the impacts of restricting condensates to two different kinds of surfaces: lipid bilayer membranes and long noncoding RNA molecules. In this seminar\, I will share two stories from my research on how both types of surfaces provide control over condensate size\, position\, and composition. Given the growing recognition that condensates associate with biological surfaces in diverse contexts\, these studies reveal broadly applicable mechanisms for the control of condensate properties. I will conclude by sharing plans for my independent lab\, launching May 2025 at Northwestern University Feinberg School of Medicine\, where we will work to decipher the “spatial code” of mRNA within cells. In particular\, we will uncover the molecular features of mRNAs that drive localization to condensates in the nucleus and cytoplasm. Using a combination of live-cell imaging and bottom-up reconstitution\, we will examine the functional impacts of condensate localization on mRNA nuclear export\, long-distance transport\, and translation. Through our work\, we aim to acquire new insights into the molecular origins of human diseases and identify new opportunities for therapy. \nHost:  Xingcheng Lin

SUMMARY:Physics Colloquium: Dan Scolnic
DESCRIPTION:Dan Scolnic\, Duke University \nTitle: The Lingering Hubble Tension and New Puzzling Measurements of Dark Energy \nAbstact: The standard model of cosmology has passed every test over the last twenty years.  Yet it remains unsatisfactory\, with 95% of the universe being dark components\, whose nature we did not understand.  Now\, there are possible ‘cracks’ in the model\, as recent observations of the local expansion rate of the universe\, parameterized by the Hubble constant\, do not match predictions using data from the Cosmic Microwave Background and our standard model.  This is the best end-to-end test of our cosmological model\, and currently\, we do not pass the test.  I will discuss my team’s Pantheon+SH0ES measurements on the local side\, and review the numerous crosschecks and tests on our data and analysis.  I will also talk about new measurements of dark energy from the Dark Energy Survey\, and compare them to other measurements and discuss implications about a possible evolution of dark energy.  Finally\, I will go over the upcoming LSST and Roman surveys and talk about how they can help answer these increasingly puzzling issues. \nHost: Rongmon Bordoloi \nBio: Dan Scolnic is an associate professor of Physics at Duke University.  Scolnic leads measurements of the expansion rate of the universe with Type Ia supernovae and other standard candles.  Scolnic also helps lead the Nancy Grace Roman Space Telescope supernova team.

SUMMARY:Physics Colloquium: Rui Sun
DESCRIPTION:Rui Sun\, NC State University \nTitle: Control Over Spin with Chirality \nAbstract: Spintronics\, an emerging field at the intersection of condensed matter physics and materials science\, harnesses the spin degree of freedom of electrons for novel electronic functionalities beyond conventional charge-based electronics\, such as spin-orbit torque magnetic random-access memory (SOT-MRAM). In the last decade\, a particularly intriguing phenomenon in this domain is the Chirality-Induced Spin Selectivity (CISS) effect\, where chiral molecules and materials preferentially transmit electrons with a specific spin orientation\, despite the absence of strong spin-orbit coupling. This effect challenges conventional spin transport mechanisms and reveals new pathways for generating and manipulating spin currents without the need for ferromagnets or heavy elements with strong spin-orbit coupling.\nIn this talk\, I will introduce the fundamental concepts of spintronics\, spin transport\, and spin dynamics. I will discuss the impact of chiral materials on spin dynamics\, and the role of chirality in spin transport. Recent experimental findings\, including our work on colossal anisotropic spin absorption in chiral metal oxides\, demonstrate how structural chirality can significantly influence nonlocal spin transport\, leading to unprecedented control over spin current. Moreover\, chirality-governed spin transport is a universal phenomenon\, extending across various chiral systems. These insights open exciting opportunities for next-generation spintronic devices\, including chiral spin filters\, spin-based logic\, and quantum information applications. \nHost: Dali Sun

SUMMARY:Physics Colloquium: Mason Porter
DESCRIPTION:Title: Quantum Networks \nAbstract: I discuss a few ideas at the interface of network science and quantum physics. A key idea in this interface is the notion of a quantum walk\, which is a generalization of a classical random walk. I will discuss the use of quantum walks to measure the importance (i.e.\, centrality) of entities in a network\, and I will illustrate how local clustering in a network can induce localization of quantum walks. Finally\, I will illustrate how quantum ideas inspire the study of networks with complex-valued weights and advocate that leveraging ideas from mathematical physics have the (insufficiently explored) potential to yield useful insights into network analysis and data analysis. \nPresented in conjunction with Mathematics Department. \n  \n

DESCRIPTION:Title: Galaxies as Probes of the Particle Physics Nature of Dark Matter \nAbstract: The hypothesis of Cold Dark Matter (CDM) has been spectacularly confirmed on the largest scales of the Universe and must now be stress-tested on sub-galactic scales.  Many well-motivated and generic alternatives to CDM can leave spectacular signatures on precisely these scales\, affecting the evolution of galaxies as well as their population statistics.  Excitingly\, over the course of the next decade\, a flood of astrophysical data will open the possibility of searching for these distinctive imprints and shedding light on key questions about dark matter.  I will review the promise of upcoming data as well as recent theory advancements for modeling dark matter physics on these scales. \nHost: Wellness and retention committee c/o Sharonda LeBlanc

SUMMARY:CMB Seminar: Tom Schroeder
DESCRIPTION:Title: Controlling crystal growth using polyelectrolytes \nAbstract: In one form or another\, polyelectrolyte additives are employed to control the formation of ionic crystals in a variety of contexts. As one example\, engineers employ them as antiscalants to prevent the buildup of minerals on the interior of pipes. In a drastically different setting — the microenvironment in animal tissues in which collagen is mineralized to form bone — biological macromolecules bearing multiple phosphate groups enable the deposition of calcium salts on the interior of nanoscale fibrous scaffolds. In these processes\, associative interactions between the polyelectrolyte and nanoscale amorphous ion clusters serve as kinetic barriers to the nucleation of stable crystals. In some contexts\, these interactions drive a phase separation process that results in the formation of a mineral-rich liquid-like precursor phase. Such precursors can be manipulated with scaffolds and capillary forces to ultimately synthesize crystalline materials in highly non-equilibrium morphologies. This talk will cover some insights and applications related to liquid precursor phases (mostly of calcium carbonate) being explored in the Schroeder lab in the Department of Textile Engineering\, Chemistry and Science. Our lab is able to manipulate such precursors using other additives to controllably trigger nucleation on-demand\, activity we are able to rationalize using thermodynamic arguments. We have also developed methods to scaffold crystal deposition using readily available substrates\, enabling the synthesis of functional materials at scale. \n  \nTom Schroeder is an Assistant Professor in the Department of Textile Engineering\, Chemistry and Science in the Wilson College of Textiles. Prior to joining NC State in 2022\, he completed a postdoc in materials science in Joanna Aizenberg’s lab at Harvard\, a Ph.D. in chemical engineering from University of Michigan (in Michael Mayer’s biophysics lab\, with which he moved from Ann Arbor to the Adolphe Merkle Institute in Switzerland for nearly 3 years)\, and a bachelor’s degree in chemistry from Northwestern. Tom is broadly interested in bioinspired materials; his other specific foci include gels and ionic circuitry.

SUMMARY:Physics Colloquium: Shelly Lesher
DESCRIPTION:Title: The Impact of Nuclear Physics on Society \nAbstract: Born in war\, nuclear science was first revealed to the world in horror. The Cold War\, power plant disasters\, and current political tensions continue to play into people’s fears of everything nuclear. But what is the scientist’s role? The author uses public scholarship to help address these fears by exploring the impact nuclear science has on society. When the Atomic Energy Commission (AEC) and Edward Teller planned to “nuke” a harbor in Point Hope Alaska\, the Iñupiat residents and local scientists fought to keep their land pristine. Find out what happened in Point Hope and how this impacts everything from nuclear testing to a possible cure for Alzheimer’s disease. \nHost: Richard Longland

SUMMARY:Physics Colloquium: Shengwang Du
DESCRIPTION:Title: Distributed Quantum Computing with Shared Quantum Gate Processing Unit \nAbstract: Due to many physical constraints\, it is extremely challenging to build a monolithic fully connected quantum computer with a very large number (N) of qubits\, in which a direct control gate operation can be performed between two arbitrary qubits. Extending from N to N+1 in such a quantum computer is more than just physically adding one more qubit. For this reason\, the cost of such a fully connected quantum computer increases exponentially as the number of qubits increases. On the other side\, connecting two N-qubit remote quantum computers classically\, the dimension of their combined Hilbert space is only 22N=2(N+1). If they are fully connected though quantum links\, the dimension of the combined Hilbert space could reach 2(2N) which is much more powerful than two independent quantum computers. Consequently\, there is a growing interest in exploring distributed quantum computing (DQC) systems that can interconnect many small-sized\, cost-effective local quantum computers. In most conventional DQC architectures\, each local quantum computer is equipped with additional communication qubits dedicated to establishing remote entanglement links. The presence of these communication qubits not only substantially increases the cost of individual local quantum computer nodes\, but also renders the entanglement-communication-based scheme inherently non-deterministic. In this work\, we propose a DQC architecture in which individual small-sized quantum computers are connected through a shared quantum gate processing unit (S-QGPU) [1]. The S-QGPU comprises a collection of hybrid two-qubit gate modules [2] for remote gate operations. In contrast to conventional entangled-communication-based DQC systems\, S-QGPU effectively pools the resources together for remote gate operations\, and thus significantly reduces the cost of not only the local quantum computers but also the overall distributed system. Moreover\, S-QGPU’s shared resources for remote gate operations enable efficient resource utilization. When not all computing qubits in the system require simultaneous remote gate operations\, S-QGPU-based DQC architecture demands fewer resources\, further decreasing the overall cost. Unlike conventional DQC architectures based on entanglement communication\, wherein remote gate operations are accomplished via teleportation or cat-entanglers [3\, 4]\, the proposed S-QGPU approach for remote gate operations is deterministic and does not depend on any measurement-based post selection. \n[1] E.

SUMMARY:Physics Colloquium: Lu Bai
DESCRIPTION:Title: Studying Chromosome Conformation and Dynamics Using Chemically Induced Chromosomal Interaction (CICI) \nAbstract: Chemically Induced Chromosomal Interaction (CICI) method developed in our lab enables induction of stable chromosome interactions. This method allows us to accurately measure the encounter time\, or the “first passage time (FPT)” of two targeted loci on the chromosome. Here\, we extracted the FPTs from different loci pairs in G1-arrested cells and uncovered distinct patterns for inter- and intra-chromosomal interactions. Specifically\, we found that intra-chromosomal pairs with comparable physical distances formed contacts more rapidly than inter-chromosomal pairs\, despite exhibiting similar diffusion rates. This difference in distance dependencies indicates an active mechanism that promotes intra-chromosomal interaction. Through targeted depletion experiments\, we identified condensin\, but not cohesin\, as the key factor driving the short encounter time observed in intra-chromosomal loci. A polymer model based on these data suggests that condensin extrudes loops at low frequency but with high speed and long processivity. Overall\, these findings reveal a new role of condensin in regulating interphase yeast genome and provide insight into the searching mechanism of cis-regulatory elements for their targets in vivo. \nHost: Xingcheng Lin
