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…
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…
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…
Asymptotics in the bi-Yang-Baxter Sigma Model
Meer Ashwinkumar, Domenico Orlando, Susanne Reffert +1
Working in a sector of large charge is a powerful tool to analytically access models that are either strongly coupled or otherwise difficult to solve explicitly. In the context of…
5d-4d Correspondence in Twisted M-theory on a Conifold
Meer Ashwinkumar, Mir Faizal, Arshid Shabir +2
We study twisted M-theory in a general conifold background, and describe it in terms of a 5d non-commutative Chern-Simons-matter theory, which is equivalent to 5d non-commutative C…
Duality Origami: Emergent Ensemble Symmetries in Holography and Swampland
Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki
We discuss the interrelations between several ideas in quantum gravity -- holography, the Swampland, and the concept of ensemble averaging. To do so, we study ensemble averages of…
