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…
Superconformal Block from Holographic Geometry
Heng-Yu Chen, Jun-ichi Sakamoto
We explicitly construct the holographic dual configuration for the four dimensional superconformal block containing half-BPS scalar primary operators by considering…
Comments on -deformed principal chiral model from 4D Chern-Simons theory
Osamu Fukushima, Jun-ichi Sakamoto, Kentaroh Yoshida
We study -deformations of principal chiral model (PCM) from the viewpoint of a 4D Chern-Simons (CS) theory. The -deformed PCM has originally been derived from the 4D CS theor…
