From Effective Temperature to Non-Boltzmann State Selection in Driven-Dissipative Quantum Criticality
Tiago Jorge, Jens Paaske, Pedro Ribeiro
Whether a nonequilibrium quantum-critical steady state can be described by an effective temperature remains an open question. We address it in a voltage-biased electronic Lipkin--M…

Critical Charge and Current Fluctuations across a Voltage-Driven Phase Transition
José F. B. Afonso, Stefan Kirchner, Pedro Ribeiro
We investigate bias-driven non-equilibrium quantum phase transitions in a paradigmatic quantum-transport setup: an interacting quantum dot coupled to non-interacting metallic leads…
