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.

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

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.

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-...

THIS SEMINAR WILL BE RESCHEDULED AT A LATER DATE.

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.

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.
