$T \bar{T}$–deformation of $q$-Yang-Mills theory

I will present the $T \bar{T}$-perturbed version of $q$-deformed two-dimensional Yang-Mills theory. I will show that the operator $T \bar{T}$ spoils the factorization of the partition function into chiral/anti-chiral sectors. On the other hand, it preserves a large $N$ third order phase transition, although modifying the phase diagram. Implications for the entanglement entropy at large $N$ will be discussed as well. I will conclude with comments on the potential applications of these results to the Bethe/gauge correspondence and to four-dimensional supersymmetric theories.

Based on joint work with Richard J. Szabo and Miguel Tierz, arXiv:2009.00657
