Intersecting Surface Operators in 6d Holomorphic Field Theories
Meer Ashwinkumar
We study intersecting surface operators in 6d holomorphic field theories with the aim of unraveling associated quantum integrable structures. We first study the intersections of su…

Integrable Deformations of the Breitenlohner-Maison Model from 4d Chern-Simons Theory
Meer Ashwinkumar, Matthias Blau
We derive integrable deformations of the 2d Breitenlohner-Maison (BM) sigma model that describes the stationary, axisymmetric sector of 4d general relativity, as well as higher-ran…

The Yang-Baxter Sigma Model from Twistor Space
Meer Ashwinkumar, Jitendra Pal
We derive a novel two-field four-dimensional integrable field theory (IFT) from 6d holomorphic Chern-Simons theory on twistor space. The four-dimensional IFT depends on a skew-symm…
