We investigate the dynamical properties of low-dimensional systems, driven by external noise sources. Specifically we consider a resistively shunted Josephson junction and a one-dimensional quantum liquid in a commensurate lattice potential, subject to 1/f noise. In absence of nonlinear coupling, we have shown previously that these systems establish a nonequilibrium critical steady state [Dalla Torre, Demler, Giamarchi, and Altman, Nat. Phys. 6, 806 (2010)]. Here, we use this state as the basis…

Quantum correlations in the one-dimensional driven dissipative XY model

We study the non-equilibrium steady state (NESS) of a driven dissipative one-dimensional system near a critical point, and explore how the quantum correlations compare to the known critical behavior

Noisy quantum phase transitions: an intuitive approach

Equilibrium thermal noise is known to destroy any quantum phase transition. What are the effects of non-equilibrium noise? In two recent papers, we have considered the specific case of a resistively

Nature of the nonequilibrium phase transition in the non-Markovian driven Dicke model.

A variant of the Dicke model where the cavity mode is lossy due to the coupling to a Markovian environment while the atomic mode is coupled to a colored bath is studied, showing that the superradiant phase transition is classical in nature, while it is genuinely nonequilibrium.

Emergent finite frequency criticality of driven-dissipative correlated lattice bosons

Critical points and phase transitions are characterized by diverging susceptibilities, reflecting the tendency of the system toward spontaneous symmetry breaking. Equilibrium statistical mechanics

Pseudothermalization in driven-dissipative non-Markovian open quantum systems

We investigate a `pseudo thermalization' effect, where an open quantum system coupled to several non-Markovian reservoirs presents an emergent thermal behaviour in spite of its coupling to a

Gaussian trajectory approach to dissipative phase transitions: The case of quadratically driven photonic lattices

We apply the Gaussian trajectories approach to the study of the critical behavior of two-dimensional dissipative arrays of nonlinear photonic cavities, in presence of two-photon driving and in

Nonequilibrium Fixed Points of Coupled Ising Models

It is shown that multicritical points in driven-dissipative systems lead to a rich and genuinely nonequ equilibrium behavior, and it is argued that this nonequilibrium behavior can be observed in cavity arrays with cross-Kerr nonlinearities.

Phase diagram of incoherently driven strongly correlated photonic lattices

We explore theoretically the nonequilibrium photonic phases of an array of coupled cavities in presence of incoherent driving and dissipation. In particular, we consider a Hubbard model system where

Non-Gaussian correlations imprinted by local dephasing in fermionic wires

We study the behavior of an extended fermionic wire coupled to a local stochastic field. Since the quantum jump operator is Hermitian and quadratic in fermionic operators, it renders the model

Keldysh approach for nonequilibrium phase transitions in quantum optics: Beyond the Dicke model in optical cavities

We investigate non-equilibrium phase transitions for driven atomic ensembles, interacting with a cavity mode, coupled to a Markovian dissipative bath. In the thermodynamic limit and at



Nonequilibrium phase diagram of a driven and dissipative many-body system

We study the nonequilibrium dynamics of a many-body bosonic system on a lattice, subject to driving and dissipation. The time evolution is described by a master equation, which we treat within a

Thermalization and dissipation in out-of-equilibrium quantum systems: A perturbative renormalization group approach

A perturbative renormalization group approach is employed to study the effect of a periodic potential on a system of one-dimensional bosons in a nonequilibrium steady state due to an initial

Bosonization of one-dimensional fermions out of equilibrium

Bosonization technique for one-dimensional fermions out of equilibrium is developed in the framework of the Keldysh action formalism. We first demonstrate how this approach is implemented for free

Mode-coupling-induced dissipative and thermal effects at long times after a quantum quench.

It is shown that even when the periodic potential is an irrelevant perturbation in equilibrium, it has important consequences on the athermal steady state as it generates a temperature as well as a dissipation and hence a finite lifetime for the bosonic modes.

Effect of suddenly turning on interactions in the Luttinger model.

The evolution of correlations in the exactly solvable Luttinger model after a suddenly switched-on interaction is analytically studied and the critical exponent that characterizes the decay of the one-particle correlation function is different from the known equilibrium exponents.

Decoherence of a superconducting qubit due to bias noise

We calculate for the current-biased Josephson junction the decoherence of the qubit state from noise and dissipation. The effect of dissipation can be entirely accounted for through a semiclassical
