Abstract

TTbar-deformations are novel ways of deforming many-body systems, which have a number of surprising properties. One of them is that integrability remains intact even after the deformations provided that the initial system is integrable. We shall leverage this fact to study transport phenomena of TTbar-deformed conformal field theories (CFTs) with the aid of generalised hydrodynamics. It turns out that we can obtain exact transport quantities in TTbar-deformed CFTs such as Drude weights and the momentum diffusion constant. We corroborate some of these findings with independent computations based on conformal perturbation and AdS/CFT correspondence.
