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 (…
Burgers Equation vs. Large Limit in -deformed Vector Model
Junichi Haruna, Katsuta Sakai, Kentaroh Yoshida
We study a -deformed vector model, which is classically equivalent to the Nambu-Goto action with static gauge. The thermal free energy density can be computed exac…
Chaotic string dynamics in deformed
Takaaki Ishii, Shodai Kushiro, Kentaroh Yoshida
Recently, Arutyunov, Bassi and Lacroix have shown that 2D non-linear sigma model with a deformed background is classically integrable [arXiv:2010.05573 [hep-th]]. This ba…
The Faddeev-Reshetikhin model from a 4D Chern-Simons theory
Osamu Fukushima, Jun-ichi Sakamoto, Kentaroh Yoshida
We derive the Faddeev-Reshetikhin (FR) model from a four-dimensional Chern- Simons theory with two order surface defects by following the work by Costello and Yamazaki [arXiv:1908.…
Yang-Baxter deformations of the AdSS supercoset sigma model from 4D Chern-Simons theory
Osamu Fukushima, Jun-ichi Sakamoto, Kentaroh Yoshida
We present homogeneous Yang-Baxter deformations of the AdSS supercoset sigma model as boundary conditions of a 4D Chern-Simons theory. We first generalize the procedu…
