Title: Driven Markovian Quantum Criticality

Abstract: In this talk I discuss the emergence of novel universal
critical behaviour in one-dimensional driven open quantum Bose gases
in the presence of diffusive Markovian noise.
Salient features are the persistence of both non-equilibrium
conditions as well as quantum coherence close to the critical point.
This provides a non-equilibrium analogue of quantum criticality,
sharply distinct from more generic driven systems where both effective
thermalisation as well as asymptotic decoherence ensue, paralleling
classical dynamical criticality.
The novel critical point is characterised by the full set of
independent critical exponents, which are extracted from a functional
renormalisation group suited for the Keldysh action.
