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.
