SUMMARY:Physics Colloquium: Mariangela Lisanti
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: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

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: 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: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
