Title: Quantum Networks Abstract: 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…
Universal Coarse Geometry of Spin Systems
Rui Sun, NC State University Title: Control Over Spin with Chirality Abstract: 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…
Dan Scolnic, Duke University Title: The Lingering Hubble Tension and New Puzzling Measurements of Dark Energy Abstact: 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…
Title: Decoding Intracellular Organization by Biomolecular Condensation Abstract: 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…
Gleb Finkelstein, Duke University Title: Multiterminal Graphene-based Josephson Junctions — a Playground for Non-linear and Quantum Physics Abstract: 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…
Title: Hyperuniformity of Disordered Network Metamaterials Derived from Hyperuniform Point Patterns Abstract: 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.…
Development of Magnetic and Neutron Systems Contributing to the Search for the Electric Dipole Moment of the Neutron
Kim Venn, University of Victoria Title: Exploring the Faintest Milky Way Satellites Abstract: 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…
Jonah Miller, Los Alamos National Lab Title: What High Fidelity Supercomputer Simulations Can Teach Us About Matter at the Highest Densities and the Origin of Heavy Elements Abstract: 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…
