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…
Voltage-Driven Breakdown of Electronic Order
Miguel M. Oliveira, Pedro Ribeiro, Stefan Kirchner
The non-thermal breakdown of a Mott insulator has been a topic of great theoretical and experimental interest with technological relevance. Recent experiments have found a sharp no…
Mixed-order symmetry-breaking quantum phase transition far from equilibrium
T. O. Puel, S. Chesi, S. Kirchner +1
We study the current-carrying steady-state of a transverse field Ising chain coupled to magnetic thermal reservoirs and obtain the non-equilibrium phase diagram as a function of th…
Finite energy spectral function of an anisotropic 2D system of coupled Hubbard chains
P. Ribeiro, P. D. Sacramento, K. Penc
We study the crossover from the one-dimensional to the two-dimensional Hubbard model in the photoemission spectra of weakly coupled chains. The chains with on-site repulsion are tr…
Entanglement in the symmetric sector of qubits
P. Ribeiro, R. Mosseri
We discuss the entanglement properties of symmetric states of qubits. The Majorana representation maps a generic such state into a system of points on a sphere. Entanglemen…
