Title: Galaxies as Probes of the Particle Physics Nature of Dark Matter Abstract: 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…

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…

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…
