IAS Physics Group Meeting

The S-matrix Bootstrap for a Custodially-Symmetric Higgs
Justin Berman
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: The S-matrix bootstrap uses analyticity, unitarity, and crossing symmetry to place nonperturbative bounds on 4-point scattering amplitudes. In my talk, I describe the application of the bootstrap to the scattering of O(4) symmetric scalars...

Rutgers University Astrophysics Colloquium

Many-fermion quantum entanglement in the high temperature superconductors and in black holes
Subir Sachdev
3:30pm|Serin Hall Rm W330, Rutgers and Zoom

Abstract: Recent decades have seen remarkable progress in the theory of many-boson quantum entanglement, which has applications to quantum spin liquids in materials and devices. But most modern quantum materials require the theory of many-fermion...

University of Pennsylvania Astrophysics Seminar

Probing the Universe’s expansion with multi-messenger astronomy
Antonella Palmese
3:30pm|U.Penn, David Rittenhouse Laboratory, 4E19

Thanks to the synergies between gravitational wave (GW) experiments, such as LIGO/Virgo/KAGRA, and electromagnetic observations of transients and galaxies, a variety of novel cosmological measurements has recently become possible. Several of these...

Mathematical Conversations

Dropping the Regulator
Peter Sarnak
6:00pm|Birch Garden, Simons Hall

As indicated by its name the regulator governs the behavior of objects, such as class numbers, in various settings. Separating it out, "the fusion problem" is a major challenge.

IAS Quantum Aspects of Black Holes Group Meeting

Geometry of the Saad Wormhole
Zhenbin Yang
11:00am|Bloomberg Hall Physics Library

Abstract: We will discuss a simple geometric construction of a wormhole that contributes a linear ramp to the late time correlators in an eternal black hole background. This is based on work in progress with Douglas Stanford.

Institute for Advanced Study Astrophysics Seminar

Magnetospheric Accretion and Ejection
Zhaohuan Zhu
11:00am|Bloomberg Lecture Hall

Magnetospheric accretion is a universal process occurring in magnetized astronomical objects, ranging from neutron stars and white dwarfs to young stars (YSOs) and planets. In the context of neutron stars, this process is linked with phenomena such...

Princeton University Thunch Talk

Discontinuous Galerkin-finite difference hybrid method for computational astrophysics
Yoonsoo Kim
12:00pm|Princeton University, Peyton Hall, Grand Central

Abstract: I will provide a brief introduction to the nodal discontinuous Galerkin (DG) method, discuss struggles of spectral-type numerical methods in handling shocks and Gibbs phenomenon, then present a DG-finite difference hybrid scheme being...

Special Year Research Seminar

On the Universality of Motivic Cohomology
Tess Bouis
1:00pm|Simonyi 101

A category of motives is an axiomatic framework in which several cohomology theories from algebraic geometry are represented. While Morel and Voevodsky's classical framework of motivic homotopy theory focused on $A^1$-invariant cohomology theories...
