Colloquium: Discoveries with the JWST, and what comes next

John C. Mather (NASA) Physics Nobel 2006
- David Rittenhouse Laboratory, A8

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)
- David Rittenhouse Laboratory, 3W2

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…



Condensed, Soft & Living Matter Seminar: Far-from-Equilibrium Statistical Physics: Information and Response in Living Matter

Zhiyue Lu (UNC)
- David Rittenhouse Laboratory, A8

Statistical mechanics, first developed for equilibrium systems, stands as one of physics' greatest triumphs. Living systems, however, operate far from equilibrium, processing information and…



CANCELLED: Astrophysics Seminar: FRB science results from CHIME

Kendrick Smith (Perimeter)
- David Rittenhouse Laboratory, 4E19

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…



Experimental Particle Physics Seminar: Studying the Higgs boson at the LHC and beyond

Liza Brost (BNL)
- David Rittenhouse Laboratory, 3W2



Dissertation Defense: "Using Novel Approaches to Improve Late-Time Cosmological Probes."

Jaemyoung (Jason) Lee
- David Rittenhouse Labs, A8



High Energy Theory Seminar: Tidal Love numbers and Tidal anomalous dimensions

Yue-Zhou Li (Princeton)
- David Rittenhouse Laboratory, 3W2

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…



Condensed, Soft & Living Matter Seminar: Robust prediction of moiré material topology

Valentin Crepel (Flatiron Institute)
- David Rittenhouse Laboratory, A8

Moiré materials have recently been envisioned as condensed-matter quantum simulators [1] due to their highly tunable low-energy properties controlled by chemical composition, stacking configurations, twist…
