### “Getting a Big Bang out of Physics” - Prof. Chris Tully

### IAS HET Seminar | Nafiz Ishtiaque, Member, School of Natural Sciences, IAS| "Relating Integrable Spin Chains to Gauge Theories via String Theory" | Wolfensohn Hall & Zoom

I will discuss some applications of brane constructions of rational integrable spin chains with Verma modules. These spin chains appear in various gauge theories.

### Special Joint Gravity Group and Gravity Initiative Seminar: Neil Cornish|Montana State| "Gravitational Wave Astronomy: Where we are at, and What’s next”

Following the first detection of a binary black hole merger in 2015, the number of gravitational wave events has grown to almost one hundred, including binary neutron star mergers and mixed black hole, neutron star mergers.

### Quantum geometry, superconductivity and superfluidity in fermionic and bosonic systems

Quantum geometry, namely quantities such as quantum metric, Berry curvature, and Chern number, have become increasingly important in understanding interacting many-body systems.

### Solid State, Atom-based Devices for Analog Quantum Simulation and Quantum Computing

NIST is using atomically precise fabrication to make single atom transistors, few-donor/quantum dot devices, and arrayed few-donor devices for analog quantum simulation (AQS). The goal of the AQS experiments is to explore the Hubbard phase space by fabricating atomically engineered materials whose properties, such as magneti

### HET Seminar | Lorenzo di Pietro, Sissa, International School for Advanced Studies| “Factorization and Global symmetry in holography” | Via Zoom

Based on 2203.09537. In the context of toy models of holography arising from 3d Chern-Simons theory, I will describe an approach in which, rather than summing over bulk geometries, one gauges a one-form global symmetry of the bulk theory.

### Encoded Silicon Qubits: A High-Performance & Scalable Platform for Quantum Computing

For quantum computers to achieve their promise, regardless of the qubit technology, significant improvements to both performance and scale are required. Quantum-dot-based qubits in silicon have recently enjoyed dramatic advances in fabrication and control techniques. The “exchange-only” modality is of particular interest, as it avoids control...

### IAS HET Seminar | Lance Dixon, Stanford University| "Scattering Amplitudes in Maximally Supersymmetric Gauge Theory and a New Duality" | Wolfensohn Hall & Zoom

Scattering amplitudes are the arena where quantum field theory directly meets collider experiments. An excellent model for scattering in QCD is provided by N=4 super-Yang-Mills theory, particularly in the planar limit of a large number of colors, where the theory becomes integrable, and amplitudes become dual to light-like polygonal Wilson-...

### Biophysics seminar: Marc Gershow, New York University| TBD

### POSTPONED!! IAS HET Seminar - Friday, April 22 - 1:45 PM - Wolfensohn Hall & Zoom - "Quantum Error Correction in SYK and Bulk Emergence" - Adam Levine, Member, School of Natural Sciences, IAS

**THIS SEMINAR WILL BE RESCHEDULED AT A LATER DATE.**

### Hamilton Colloquium Series, Clifford V. Johnson, "Wigner Meets ’t Hooft Near the Black Hole Horizon". Postponed

There has been exciting recent progress in the study of the quantum nature of black holes through the use of certain exactly solvable models.

### PICSciE's Graduate Certificate in Computational Science & Engineering Spring Colloquium - Thursday, April 28, 2:00–4:00 PM, 120 Lewis Science Library

### Hamilton Colloquium Series, Marc Kamionkowski, Johns Hopkins University, "News from Cosmic Dark Sectors"

Cosmologists are proud of the standard cosmological model that has been developed to account for a wealth of disparate features of the Universe. The model requires, though, that we postulate the existence of some collisionless dark matter and also dark energy, a negative-pressure substance. The nature of both of these dark constituents is a...

### Panel on Faculty Job Applications

### Claudia Felser

### Biophysics seminar: Andrea Liu, University of Pennsylvania| How Materials Can Learn

How does learning occur? Neural networks learn via optimization, where a loss function is minimized by a computer to achieve the desired result. But physical networks such as mechanical spring networks or flow networks have no central processor so they cannot minimize such a loss function.

### IAS HET Seminar - Friday, April 22 - 1:45 PM - Wolfensohn Hall & Zoom - "Localized Collisions and the Black Hole Interior" - Felix Haehl, IAS

We study collisions of localized shockwaves behind the horizon of the eternal AdS black hole. We give a holographic boundary description in terms of the overlap of two growing perturbations in a shared quantum circuit.

### Donald R. Hamilton Lecture, Thurs. April 21, 2022, Steven M. Girvin (Yale University), "Progress and Prospects for the Second Quantum Revolution"

The first quantum revolution brought us the great technological advances of the 20th century—the transistor, the laser, the atomic clock and GPS, the global positioning system. We now realize that this 20th century hardware does not take full advantage of the power of quantum machines.

### HEP Seminar- Luca Mastrolorenzo-CERN-"Unveiling the Higgs Boson's Charm with the CMS Experiment"

Probing the Yukawa couplings is paramount to understand the role played by the Higgs boson in the Standard Model. Ten years after the discovery of the Higgs boson, all the Yukawa couplings to the third generation of fermions have been measured.
