Criticality in transport through the quantum Ising chain — •Malte Vogl, Gernot Schaller, and Tobias Brandes — Institut für Theoretische Physik, TU Berlin

We consider thermal transport between two reservoirs coupled by a quantum Ising chain as a model for non-equilibrium physics induced in quantum-critical many-body systems. By deriving rate equations based on exact expressions for the quasi-particle pairs generated during the transport, we observe signatures of the underlying quantum phase transition in the steady-state energy current already at finite and different reservoir temperatures.
