Non-Abelian Toda field theories from a 4D Chern-Simons theory
Osamu Fukushima, Jun-ichi Sakamoto, Kentaroh Yoshida
We derive non-abelian Toda field theories (NATFTs) from a 4d Chern-Simons (CS) theory with two order defects by employing a certain asymptotic boundary condition. The 4d CS theory…

Integrable deformed sigma models from 4D Chern-Simons theory
Osamu Fukushima, Jun-ichi Sakamoto, Kentaroh Yoshida
Recently, a variety of deformed manifolds, with which 2D non-linear sigma models (NLSMs) are classically integrable, have been presented by Arutyunov, Bassi and Lacroix (…
