High Energy Theory Seminar: Gravitational waves with astrometry in the Gaia era
Deyan Mihaylov (Case Western Reserve University)
Gravitational waves have a periodic effect on the apparent positions of stars on the sky. This effect can be quantified and ultra-precise astrometric measurements (like the ones from Gaia)…
Condensed, Soft & Living Matter Seminar: Quantum Control of Quantum Materials
Matteo Mitrano (Harvard)
Coherently engineering quantum states with light is a key frontier in the control of quantum materials. Over the last two decades, ultrafast lasers have revealed a variety of emergent topological, magnetic, and…
Colloquium: Discoveries with the JWST, and what comes next
John C. Mather (NASA) Physics Nobel 2006
The JWST, with its 6.5 m hexagonal mirror and its 4 infrared instruments, has yielded remarkable surprises. The first galaxies are brighter and hotter than expected, and they aren’t round, but are elongated…
High Energy Theory Seminar: Comments on the density matrix of the universe in two dimensional quantum cosmology
Finn Larsen (UMichigan)
I discuss work in progress on obtaining a reasonable density matrix of the universe in two dimensional quantum cosmology. I will do so by comparing aspects of the Hilbert space of closed universes in JT gravity…
CANCELLED: Astrophysics Seminar: FRB science results from CHIME
Kendrick Smith (Perimeter)
Fast radio bursts (FRBs) are a recently discovered, poorly understood class of transient event, and understanding their origin has become a central problem in astrophysics. I will present FRB science results…
Condensed, Soft & Living Matter Seminar: Far-from-Equilibrium Statistical Physics: Information and Response in Living Matter
Zhiyue Lu (UNC)
Statistical mechanics, first developed for equilibrium systems, stands as one of physics' greatest triumphs. Living systems, however, operate far from equilibrium, processing information and…
High Energy Theory Seminar: Tidal Love numbers and Tidal anomalous dimensions
Yue-Zhou Li (Princeton)
In this talk, I will briefly review the worldline effective field theory (EFT) formalism for classical gravitational physics. Using worldline EFT, I will provide a framework for understanding the gravitational…
