Ultralocal Lax connection for para-complex -cosets
Francois Delduc, Takashi Kameyama, Sylvain Lacroix +2
We consider -models on para-complex -cosets, which are analogues of those on complex homogeneous target spaces considered recently by D. Bykov. For these models, w…
Three-parameter integrable deformation of Z_4 permutation supercosets
Francois Delduc, Ben Hoare, Takashi Kameyama +2
A three-parameter integrable deformation of permutation supercosets is constructed. These supercosets are of the form where is the bos…
Combining the bi-Yang-Baxter deformation, the Wess-Zumino term and TsT transformations in one integrable sigma-model
Francois Delduc, Ben Hoare, Takashi Kameyama +1
A multi-parameter integrable deformation of the principal chiral model is presented. The Yang-Baxter and bi-Yang-Baxter sigma-models, the principal chiral model plus a Wess-Zumino…
Affine q-deformed symmetry and the classical Yang-Baxter sigma-model
Francois Delduc, Takashi Kameyama, Marc Magro +1
The Yang-Baxter -model is an integrable deformation of the principal chiral model on a Lie group . The deformation breaks the symmetry to $U(1)^{\textrm{rank}(G)…
Generalized quark-antiquark potentials from a -deformed AdSS background
Takashi Kameyama, Kentaroh Yoshida
We study minimal surfaces with a single cusp in a -deformed AdSS background. The cusp is composed of two half-lines with an arbitrary angle and is realized on a su…
Lax pairs on Yang-Baxter deformed backgrounds
Takashi Kameyama, Hideki Kyono, Jun-ichi Sakamoto +1
We explicitly derive Lax pairs for string theories on Yang-Baxter deformed backgrounds, 1) gravity duals for noncommutative gauge theories, 2) -deformations of S, 3) Schrödi…
Minimal surfaces in -deformed AdSS with Poincare coordinates
Takashi Kameyama, Kentaroh Yoshida
We study minimal surfaces in -deformed AdSS with a new coordinate system introduced in the previous work 1408.2189. In this letter, we introduce Poincare coordinat…
A new coordinate system for q-deformed AdS_5 x S^5 and classical string solutions
Takashi Kameyama, Kentaroh Yoshida
We study a GKP-like classical string solution on a q-deformed AdS_5 x S^5 background and argue the spacetime structure by using it as a probe. The solution cannot stretch beyond th…
Anisotropic Landau-Lifshitz sigma models from q-deformed AdS_5 x S^5 superstrings
Takashi Kameyama, Kentaroh Yoshida
We consider bosonic subsectors of the q-deformed AdS_5 x S^5 superstring action and study the classical integrable structure of anisotropic Landau-Lifshitz sigma models (LLSMs) der…
String theories on warped AdS backgrounds and integrable deformations of spin chains
Takashi Kameyama, Kentaroh Yoshida
We study integrable deformations of AdS/CFT by focusing upon three kinds of warped AdS_3 geometries, 1) space-like warped AdS_3, 2) time-like warped AdS_3 and 3) null warped AdS_3.…
