Titre |
Energy flow in non-equilibrium conformal field theory |
|
Résumé |
We shall discuss properties of the energy current and its fluctuations in
quantum gapless 1d systems far from equilibrium modeled by conformal field theory,
where two separated halves are prepared at distinct temperatures and glued together at
a point contact. We give a general description of such non-equilibrium steady states in
terms of quantum field theory data. We compute the large deviation function of energy
transfer through the contact. These are universal and satisfy fluctuation relations. We
provide a simple representation of these quantum fluctuations in terms of classical.
Poisson processes whose intensities are proportional to Boltzmann weights. |
