Abstract:
Yang-Baxter deformations are integrable deformations of 2-d non-linear sigma models. Some well-known integrable backgrounds can be reproduced as Yang-Baxter deformations of sigma models on AdS_5 x S^5 or Minkowski spacetimes. So far, we only know the deformed metric and NSNS 2-form and we don’t know the deformed RR fields or dilaton. Recently, however, some deformations of AdS_5 x S^5 including fermionic sector are calculated and it enable us to read RR fields or dilaton. In this talk, I introduce the results of the calculation including fermionic sector.
