HY2W04 - Statistical mechanics, integrability and dispersive hydrodynamics

In recent years TTbar-deformed conformal field theories (CFTs) have attracted considerable interests due to their surprisingly rich structures. Although a great deal about TTbar-deformed CFTs has been already known, their dynamical aspects still remain large unexplored. In this talk I will discuss transport phenomena in TTbar-deformed CFTs, and compute several transport quantities such as the energy Drude weight and momentum diffusion constant. It turns out that energies of right and left movers in a TTbar-deformed CFT are transported by the simplest possible generalized hydrodynamic equation, which happens to also describe soliton transport in a cellular automaton called Rule 54.
