TTbar and Other Solvable Deformations of Quantum Field Theories: April 8 – 12, 2019

Organized by: Mark Mezei, Stefano Negro, Alexander Zamolodchikov, and Zohar Komargodski

The workshop will be devoted to the recent exciting developments in the investigation of irrelevant deformations in QFT. Solvable examples such as $T\bar{T}$-deformed two-dimensional QFTs and their generalizations have attracted attention across the whole spectrum of high energy theory. The purpose of the workshop is thus to bring together experts from the different fields of integrable field theories, conformal field theory and quantum gravity, in order to encourage the exchange of ideas, spur cross-subject collaborations and establish new directions. Given the variety of different approaches to the topic, the workshop will combine research talks with longer introductory lectures.
