Condensed Matter Seminar: "Topological Origin of Equatorial Waves"
Brad Marston, Brown University
Topology sheds new light on the emergence of unidirectional edge waves in a variety of physical systems, from condensed matter to artificial lattices. Waves observed in geophysical flows are also robust to…
Astronomy seminar: "Reverse Engineering the local Universe"
Edoardo Carlesi, IAP Potsdam
Constrained simulations (CS) provide a powerful alternative approach to the random-phase Initial Conditions (ICs) cosmological simulations. In this method, galaxy peculiar velocity measurements are used to…
Special Soft Matter Seminar: "Physical interactions reduce the power of natural selection in growing yeast colonies"
Andrea Giometto, Harvard University
Microbial populations often assemble in dense populations in which proliferating individuals exert mechanical forces on the nearby cells.
Department Colloquium
Speakers: Robyn Sanderson, Liang Wu, Bo Zhen, University of Pennsylvania
Robyn Sanderson: "What can a billion Milky Way stars tell us about dark matter?"
Liang Wu: "Therahertz studies on symmetry and topology in quantum materials"
Bo Zhen: "Topological photonics on the nano…

Astronomy seminar: "Stellar Forensics with the Most Powerful Explosions in the Universe"
Maryam Modjaz, New York University
Supernovae (SNe) and Long-duration Gamma-ray Bursts (GRBs) are exploding stars and constitute the most powerful explosions in the universe. Since they are visible over large cosmological distances, release elements…
High Energy Theory Seminar: "Pulling the Holographic Boundary into the Bulk"
Yasunori Nomura, University of California Berkeley
Special High Energy Theory Seminar: "Primordial black holes as dark matter"
Alex Kusenko, UCLA
I will discuss new and rather generic scenarios for production of black holes in the early universe. In some mass range, such black holes can account for all dark matter. Primordial black holes can also contribute…
