Sommaire:

The TTbar deformation is a universal irrelevant deformation of arbitrary 2d QFTs. It preserves symmetries (hence integrability when starting from an integrable theory), and energy levels on a circle obey the Burgers equation as a function of the deformation parameter. I will explain how we generalized this differential equation to antisymmetric combinations of conserved currents and/or stress-tensor: energy levels and charges also obey a hydrodynamic transport equation. We solve it for deformations of CFTs. Interestingly, the Virasoro or Kac-Moody symmetries are realized non-locally in deformed CFTs. Time-permitting I will mention supersymmetric or higher-dimensional versions.
