IAS High Energy Theory Seminar

Topological Order in Noisy Quantum Systems
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: Quantum condensed matter has traditionally focused on ground states and equilibrium properties of spatially extended systems, such as electrons in crystalline materials. However, the advent of noisy-intermediate-scale-quantum (NISQ)...

No Stone Unturned: A Comprehensive Approach to New Physics Searches at Colliders
Cari Cesarotti
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: Despite the undeniable success of the Large Hadron Collider (LHC), Beyond the Standard Model (BSM) physics remains elusive. In this talk, I will outline a multifaceted strategy to maximize discovery potential at current and future high...

Supertranslation(s) from Scattering Amplitudes
Radu Roiban
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: On-shell methods have found a new application to local observables such as asymptotic radiation fields and gravitational waveforms. While these observables are invariant under small gauge transformations, they are known to depend on a...

Complex Chern-Simons Theory and Schur Quantization
Davide Gaiotto
11:00am|Rubenstein Commons Meeting Room 5 & Zoom

Abstract: I will describe the relationship between the Schur indices of 4d N=2 SQFTs of class S and the quantization of Chern-Simons theory with complex gauge group.

Periodic Dilaton Gravity
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: I will discuss dilaton gravity with a sine potential, where periodic shifts of the dilaton (that leave the potential invariant) are treated as a redundancy. Most things I will say hold true for generic periodic potentials, but the sine...

The Spin SYK Model
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: We analyze a model of qubits which we argue has an emergent quantum gravitational description similar to the fermionic Sachdev-Ye-Kitaev (SYK) model. The model we consider is known as the quantum $q$-spin model because it features $q$...

Non-Invertible Symmetries, Boundary Conditions, and Topological Field Theory
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: In recent years, there have been various activities trying to better understand the interplay between non-invertible global symmetries and boundary conditions in quantum field theories, with applications ranging from scattering of solitons...

The Complex Liouville String
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: I will introduce a new 2d gravity/matrix integral duality. The bulk theory is a two-dimensional string theory defined by coupling two copies of Liouville CFT with central charges c = 13 ± is on the worldsheet. We call this string theory...

't Hooft Anomaly Detection in 2+1d Lattice Systems
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: I will discuss two methods for diagnosing ’t Hooft anomalies of internal symmetries in 2+1d lattice systems. Anomalous symmetries of this kind arise naturally at the boundary of 3+1D symmetry-protected topological phases, and are known to...

Algebra of the Infrared with Twisted Masses
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: The Gaiotto-Moore-Witten "Algebra of the Infrared" allows one to construct the category of supersymmetric boundary conditions for a wide class of massive N=(2,2) QFTs in two dimensions. In particular, it applies to N=(2,2) QFTs defined by...
