  • Calibrated entanglement entropy 
    Bakhmatov I.; Deger N.; Gutowski J.; Colgáin E.; Yavartanoo H. (2017)
    © 2017, The Author(s). The Ryu-Takayanagi prescription reduces the problem of calculating entanglement entropy in CFTs to the determination of minimal surfaces in a dual anti-de Sitter geometry. For 3D gravity theories and ...
  • Tri-vector deformations in d = 11 supergravity 
    Bakhmatov I.; Deger N.; Musaev E.; Colgáin E.; Sheikh-Jabbari M. (2019)
    © 2019, The Author(s). We construct a d = 11 supergravity analogue of the open-closed string map in the context of SL(5) Exceptional Field Theory (ExFT). The deformation parameter tri-vector Ω generalizes the non-commutativity ...
  • Yang-Baxter σ -models, conformal twists, and noncommutative Yang-Mills theory 
    Araujo T.; Bakhmatov I.; Colgáin E.; Sakamoto J.; Sheikh-Jabbari M.; Yoshida K. (2017)
    © 2017 American Physical Society.The Yang-Baxter σ-model is a systematic way to generate integrable deformations of AdS5×S5. We recast the deformations as seen by open strings, where the metric is undeformed AdS5×S5 with ...
