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…
Geometry of the spectral parameter and renormalisation of integrable -models
Sylvain Lacroix, Anders Wallberg
In the past few years, the unifying frameworks of 4-dimensional Chern-Simons theory and affine Gaudin models have allowed for the systematic construction of a large family of integ…
An elliptic integrable deformation of the Principal Chiral Model
Sylvain Lacroix, Anders Wallberg
We introduce a new elliptic integrable -model in the form of a two-parameter deformation of the Principal Chiral Model on the group , generalising a c…
