Description

Many one-dimensional quantum systems possess phases with low-energy excitations described by Conformal Field Theory. Examples are carbon nanotubes, quantum Hall edge currents or XXZ spin-chains. Since (1+1)d conformal transformations can map homogeneous systems to nonhomogeneous ones, CFT may be employed to describe certain nonequilibrium situations. I shall discuss how it explains and generalizes the recent results of Langmann-Lebowitz-Mastropietro-Moosavi, Phys. Rev. B 95, 235142 (2017), about the dynamics of states with a preimposed temperature profile in the Luttinger model of 1d electrons.
