Title:
“TTbar-deformed conformal field theories out of equilibrium”
Abstract:
In the seminar I will discuss out-of-equilibrium properties of conformal field theories that are deformed by the TTbar-deformation from two perspectives: integrability and holography. I will focus on the energy and momentum Drude weights and diffusion constants, as well as the nonequilibrium steady states, which emerge after the inhomogeneous quench. Surprisingly, the transport coefficients and nonequilibrium steady states admit a universal closed form expressions, which do not depend on the field content of the conformal field theory. The matching of the results between the two methods serves as the first check of the TTbar-deformed holographic correspondence from the dynamical standpoint, and establishes the connection between the generalized hydrodynamics and holography.
