On the Integrable Structure of the SU(2) Wess-Zumino-Novikov-Witten Model
Sylvain Lacroix, Adrien Molines
This paper is devoted to the quantum integrable structure of Wess-Zumino-Novikov-Witten models, formed by an infinite number of commuting Integrals of Motion (IMs) in their current…
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…
