Speaker(s):

Hamilton Colloquium Series, Frans Pretorius, Princeton University, "Gravitational Wave Astrophysics: A Status Report"

Thu, Feb 10, 2022, 4:00 pm

I will review the state of the field of gravitational wave astrophysics, framing the challenges, current observations, and future prospects within the context of the predictions of Einstein's theory of general relativity.

Virtual Biophysics Seminar: Zvonimir Dogic, UCSB, Brandeis|Sculpting liquid interfaces with active stresses

Mon, Feb 7, 2022, 12:30 pm

Controlling interfacial structure and dynamics of phase separating fluid mixtures is key to creating diverse functional materials. Traditionally, this is accomplished by controlling interface chemistry, through the presence of surface-modifying amphiphilic agents.

Audience: A free lecture open to the public.

PGI Spring Seminar|Virtual Series| Jan Sbierski |University of Edinburgh|"The Strong Cosmic Censorship Conjecture and Singularities Inside Rotating Black Holes"

Mon, Feb 7, 2022, 12:30 pm

Abstract: One can paraphrase Penrose’s strong cosmic censorship conjecture as stating that general relativity is generically a deterministic theory. While the full conjecture remains wide open there has long been evidence pointing towards its validity at least for small perturbations of exact rotating Kerr black holes.

Tackling Quantum Many-body Problems with (Artificial) Intelligence

Tue, Feb 1, 2022, 1:00 pm

Abstract: New quantum simulation platforms provide an unprecedented microscopic perspective on the structure of strongly correlated quantum matter. This allows to revisit decade-old problems from a fresh perspective, such as the two-dimensional Fermi-Hubbard model, believed to describe the physics underlying high-temperature superconductivity...

IAS HET SEMINAR | Javier Magan, University of Pennsylvania | "A New Look at Completeness and Generalized Symmetries" | Wolfensohn Hall (behind Bloomberg Hall) & Zoom

Mon, Dec 20, 2021, 2:30 pm

We describe a general principle of completeness in QFT. It asserts that the physical observable algebras produced by local degrees of freedom are the maximal ones compatible with causality. We elaborate on equivalent statements to this principle such as the non-existence of generalized symmetries and the uniqueness of the net of algebras.

HET Seminar | Severin Lust, Harvard | "The Tadpole Problem" | PCTS 407 & via Zoom

Mon, Dec 13, 2021, 2:30 pm

I will discuss string theory compactifications where a large number of moduli is stabilized by fluxes. I will present a conjecture which rules out the stabilization of all complex-structure moduli in F-theory at a generic point in moduli space by fluxes that satisfy the tadpole cancellation condition. Evidence for this conjecture comes from...

PQI seminar: "Correlated and Topological States in Twisted Graphene Multilayers"

Mon, Dec 13, 2021, 1:30 pm

Moiré materials, stacked 2D atomic layers with a small twist angle or a slight lattice mismatch, have become emerging platforms to study the physics of correlation, topology, and the interplay between the two.

PGI Fall Seminar Series|Alexander (Sasha) Philippov|Flatiron Institute| "Dynamics of Collisionless Plasmas and Flares at the Event Horizon"

Mon, Dec 13, 2021, 12:30 pm

Abstract: Supermassive black holes create powerful jets of radiation and plasma particles that move close to the speed of light. The answers to the questions “how exactly are jets powered by energy extraction from a black hole” and “what are the processes that energize plasma particles” are crucial to understanding the observed activity.
