dc.description.abstract |
We study out-of-equilibrium energy transport in a quantum critical fluid with
Lifshitz scaling symmetry following a local quench between two semi-infinite fluid reservoirs.
The late time energy flow is universal and is accommodated via a steady state occupying an
expanding central region between outgoing shock and rarefaction waves. We consider the
admissibility and entropy conditions for the formation of such a non-equilibrium steady
state for a general dynamical critical exponent z in arbitrary dimensions and solve the
associated Riemann problem. The Lifshitz fluid with z = 2 can be obtained from a Galilean
boost invariant field theory and the non-equilibrium steady state is identified as a boosted
thermal state. A Lifshitz fluid with generic z is scale invariant but without boost symmetry
and in this case the non-equilibrium steady state is genuinely non-thermal. |
