HET Seminar | Netta Engelhardt, MIT | "Finding Pythons in Unexpected Places" | Zoom

Mon, Nov 29, 2021, 2:30 pm
Speaker(s):

PGI Fall Seminar Series| Aaron Held| Princeton University|"Black Holes Beyond General Relativity: Shadows, Stability, and Nonlinear Evolution"

Mon, Nov 29, 2021, 12:30 pm

Abstract:

Guided by the principles of effective field theory, I will discuss three consecutive avenues to constrain physics beyond General Relativity with black-hole observations.

HET Seminar | David Meltzer, Cornell | "Dispersion Formulas for AdS/CFT and Inflation" | Zoom

Mon, Nov 22, 2021, 2:30 pm

Dispersion formulas explain how fundamental consistency conditions, such as causality and unitarity, constrain low-energy physical observables. In this talk I will discuss how dispersion formulas in Minkowski, de Sitter, and Anti-de Sitter space are related.

PGI Fall Seminar Series|Hsin-Yu Chen-Einstein Fellow, MIT|"Gravitational-wave Multimessenger Observations from the Production of Gold to the Expansion of the Universe"

Mon, Nov 22, 2021, 12:30 pm

Over last six years, the LIGO-Virgo detections of gravitational waves from compact binary mergers have underlined their promise as an independent and powerful tool to explore the Universe.

EDI seminar with Kasey Wagoner: "Simons-NSBP Scholars Program"

Wed, Nov 17, 2021, 4:00 pm

Please join us for the first in-person installment of the Seminar Series on Equity, Diversity and Inclusion hosted by the Department of Physics and the Department of Astrophysics. Guest speaker, Kasey Wagoner, will discuss the Simons-NSBP Scholars Program.

Fast Scramblers: from Black Holes to Computation on Encrypted Data

Tue, Nov 16, 2021, 12:30 pm

We examine the scrambling speed of random reversible classical circuits with long-range gates. In particular, we ask the following question: how short can a classical reversible circuit be and still represent ciphers that cannot be distinguished from a random permutation with a polynomial number of queries.

IAS HET Seminar | Shai Chester, Weizmann Institute of Science | "Bootstrapping N = 4 super-Yang-Mills on the conformal manifold" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom

Mon, Nov 15, 2021, 2:30 pm

Abstract:  We study the = 4 SYM stress tensor multiplet 4-point function for any value of the complexified coupling tau, and in principle any gauge group (we focus on SU(2) and SU(3) for simplicity).

Speaker(s):

Biophysics Seminar: Jeff Gore, Massachusetts Institute of Technology| Emergent phases of ecological diversity and dynamics mapped in microcosms

Mon, Nov 15, 2021, 12:30 pm

Natural ecological communities display striking features, such as high biodiversity and a wide range of dynamics, that have been difficult to explain in a unified framework.

Audience: A free lecture open to the public.

PGI Fall Seminar Series| Stefan Czimek| Brown University|"The Characteristic Gluing Problem of General Relativity"

Mon, Nov 15, 2021, 12:30 pm

In this talk, we introduce and solve the characteristic gluing problem for the Einstein vacuum equations. We prove that obstructions to characteristic gluing come from an infinite-dimensional space of conservation laws along null hypersurfaces for the linearized equations at Minkowski.

IAS HET Seminar | Ahsan Z Khan, Member, School of Natural Sciences, IAS | "TBA" | Wolfensohn Hall (behind Bloomberg Hall) & on Zoom

Hamilton Colloquium Series, Subir Sachdev, Harvard University, "Planckian Metals and Black Holes"

Thu, Nov 11, 2021, 4:00 pm

Many modern materials feature a “Planckian metal”: a phase of electronic quantum matter without quasiparticle excitations, and relaxation in a time of order Planck's constant divided by the absolute temperature.

Speaker(s):

High Energy Physics Seminar- Xin Qian-BNL-"Search for an Anomalous Excess in Neutrino-Induced Interactions in the MicroBooNE Liquid Argon Time Projection Chamber"

Thu, Nov 11, 2021, 2:00 pm to 3:30 pm

   The MicroBooNE experiment was designed primarily to explore the nature of the previously observed low-energy excess in electron neutrino candidates in the MiniBooNE experiment located in the Booster Neutrino Beamline at Fermi National Accelerator Laboratory.

PRISM/PCCM SEMINAR: Expanding the Compositional and Microstructural Space of Layered and 2D Materials (MAX phases and MXenes)

Wed, Nov 10, 2021, 12:00 pm

Please join us Wednesday, Nov. 10, 2021, at 12:00 noon in the Bowen Hall Auditorium for the next seminar of the PRISM/PCCM Fall ’21 Seminar Series featuring Prof. Christina Birkel of Arizona State University. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.

Speaker(s):

Mathematical Physics Seminar, Tue Nov. 9, 4:30 p.m. Jadwin A-06 - Simon Becker, Courant Institute, "Mathematical Properties of Twisted Bilayer Graphene"

Tue, Nov 9, 2021, 4:30 pm

Twistronics is the study of how the angle (the twist) between layers of two-dimensional materials can change their electronic structure.

Pseudo-Gauge Field in Dirac/Weyl Materials/ Chaoxing Liu/ Pennsylvania State University

HET Seminar | Minjae Cho | "A few applications of String Field Theory" | PCTS 407 & Zoom

Mon, Nov 8, 2021, 2:30 pm

String field theory is usually considered to be a difficult and complicated object to understand and study. However, due to its field-theoretic nature, it provides a useful framework to address physical questions which are in particular natural from field theory perspective.
