Time-Dependent Integrability from Gauge Theory, I
Shota Komatsu, Jun-ichi Sakamoto, Anders Wallberg +1
Solvable time-dependent systems provide important settings for studying non-equilibrium physics, where exact results are rare. They are also useful for benchmarking quantum simulat…

Crosscap Defects
Nadav Drukker, Shota Komatsu, Anders Wallberg
We introduce a novel class of defects, termed crosscap defects, in conformal field theory (CFT) in general dimensions. These arise from quotienting the spacetime by a automor…

1-loop renormalisability of integrable sigma-models from 4d Chern-Simons theory
Sylvain Lacroix, Nat Levine, Anders Wallberg
Large families of integrable 2d sigma-models have been constructed at the classical level, partly motivated by the utility of integrability on the string worldsheet. It is natural…
