In August, 157 participants from 10 countries gathered at the Institute for the initial focus weeks of a workshop on Quantum Information and Physics. The workshop, which will continue through October 31, 2024, considers the relation of quantum complexity to physical systems such as many-body problems in quantum simulators, condensed matter physics, quantum field theory, and quantum gravity.

From July 8–26, the annual Prospects in Theoretical Physics (PiTP) program, an intensive workshop for advanced graduate students and postdoctoral scholars, took place at IAS. This year, the program brought together 213 participants from over 20 countries to discuss ultra-quantum matter.

Prospects in Theoretical Physics (PiTP), an intensive two-week summer program for advanced graduate students and postdoctoral scholars, took place from July 10–21 this year, the first meeting since COVID-19 struck in 2020.

In 2014, Nathan Seiberg, Charles Simonyi Professor in the School of Natural Sciences, "demonstrated that the most important symmetries of 20th-century physics could be extended more broadly to apply in quantum field theory, the basic theoretical framework in which physicists work today."

"Edward Witten has spent almost 50 years at the forefront of theoretical and mathematical physics. Here he describes how the LHC and other recent results have impacted his view on nature, and asks whether naturalness is still a useful guide for the field."

Theorists are in a frenzy over “fractons,” bizarre, but potentially useful, hypothetical particles that can only move in combination with one another.
