High Energy Theory | Joao Penedones, EPFL | "S-matrix Bootstrap for Effective Field Theories"

High Energy Theory | Joao Penedones, EPFL | "S-matrix Bootstrap for Effective Field Theories"
Mon, Nov 11, 2019, 2:30 pm

I will explain how the S-matrix Bootstrap for massless particles can be used to constrain the space of Effective Field Theories (EFT). In particular, I will discuss the S-matrix bootstrap for massless particles in unitary, relativistic two dimensional quantum field theories.

Audience: A free lecture open to the public.

HET Seminar | Callum Jones, U of Michigan | "Born-Infeld Electrodynamics at One-Loop” | Jadwin A06
Tue, Nov 5, 2019, 3:00 pm

The Born-Infeld model is an effective field theory of central importance describing the low-energy dynamics of massless gauge bosons on the world-volume of D-branes. Though it is in many ways an exceptional model of nonlinear electrodynamics, several aspects of the physics of the Born-Infeld model remain mysterious.

Gravity Initiative Lunch, Barak Zackay | IAS "Detecting Gravitational Waves With Disparate Detector Responses: Two New Binary Black Hole Mergers"

Gravity Initiative Lunch, Barak Zackay | IAS "Detecting Gravitational Waves With Disparate Detector Responses: Two New Binary Black Hole Mergers"
Mon, Nov 4, 2019, 12:00 pm

Abstract:
I will describe our continuing work for extracting the most of the LIGO-VIRGO data.
In this talk, I will discuss the process that was used to characterize the impact of non-Gaussian phenomena (so called 'Glitches')
I will then discuss the process that exploited the found properties in order to rank candidates...

Physics Group Meeting | Nafiz Ishtiaque, IAS | “Topological Holography” | Bloomberg Hall Physics Library

Physics Group Meeting | Nafiz Ishtiaque, IAS | “Topological Holography” | Bloomberg Hall Physics Library
Wed, Oct 30, 2019, 1:45 pm

We consider supersymmetric twist and omega deformation of a type IIB brane setup involving N D3 and K D5 branes. In the large N limit, this leads to a holographic duality between two topological/holomorphic theories. We compute certain operator algebras from both sides of this topological holographic duality and find the result consistent with...

Math Physics | Martin Fraas, Virginia Tech | "A many-body Fredholm index for ground state spaces and Abelian anyons" | Jadwin A06
Tue, Oct 29, 2019, 4:30 pm

We propose a many-body index that extends Fredholm index theory to many-body systems. The index is defined for any charge-conserving system with a topologically ordered p-dimensional ground state sector. The index is fractional with the denominator given by p.

HET Seminar | Tom Hartman, Cornell University | "Dynamical Constraints on RG Flows and Cosmology” | Bloomberg Lecture Hall

HET Seminar | Tom Hartman, Cornell University | "Dynamical Constraints on RG Flows and Cosmology” | Bloomberg Lecture Hall
Mon, Oct 28, 2019, 2:30 pm

I will discuss time-dependent probes of the renormalization group, and derive new constraints that govern the spread of local operators in holographic theories. The same methods lead to sum rules for inflationary correlators, relating observables, like the speed of sound during inflation, to properties of the UV theory.

FPO - Amanda Stevie Bergman - "Commissioning the Spider-2 Instrument and Spider-1 Low-Level Analysis"
Fri, Oct 25, 2019, 2:00 pm

The SPIDER instrument is a balloon-borne polarimeter designed to measure the primordial B-mode polarization in the cosmic microwave background (CMB). Theories of the very early universe predict that physical processes in the first fraction of a second after the Big Bang sourced large gravitational waves.

Tue, Oct 22, 2019, 4:00 pm

Functional methods, in particular efficient reorganization of the one-loop effective action, have recently made a reappearance in simplifying the problem of computing matching and running effects in Lorentz-invariant effective field theories (EFTs) such as the Standard Model Effective Field Theory.
