Abstract The quantum regression theorem states that the correlations of a system at two different times are governed by the same equations of motion as the single-time averages. This provides a powerful framework for the investigation of the intrinsi

The study of quantum many-body physics in Liouvillian open quantum systems becomes increasingly important with the recent progress in experimental control on dissipative systems and their exploitation for technological purposes. A central question in

We apply the Gaussian trajectories approach to the study of the critical behavior of two-dimensional dissipative arrays of nonlinear photonic cavities, in the presence of two-photon driving and in regimes of sizable loss rates. In spite of the highly

We construct a class of variational methods for the study of open quantum systems based on Gaussian ansatzes for the quantum trajectory formalism. Gaussianity in the conjugate position and momentum quadratures is distinguished from Gaussianity in den

We study numerically the motion of vortices in nonequilibrium Bose–Einstein condensates, that are described by a generalized Gross–Pitaevskii equation. We analyze how the vortex properties are modified when moving away under deviation from equili

Revealing universal behaviours is a hallmark of statistical physics. Phenomena such as the stochastic growth of crystalline surfaces(1) and of interfaces in bacterial colonies(2), and spin transport in quantum magnets(3-6) all belong to the same univ

Physical review A
We investigate theoretically the evolution of the vortex number in an array of photon condensates that is brought from an incoherent low-density state to a coherent high-density state by a sudden change in the pumping laser intensity. We analyze how

We report the first observation of superfluid cavity photons. Remarkably, the superfluid state emerges in a steady state and at room temperature, due to the strong thermo-optical nonlinearity of our oil-filled cavity.

We present a theoretical study of a Berezinskii-Kosterlitz-Thouless-like phase transition in lattices of nonequilibrium photon condensates. Starting from linearized fluctuation theory and the properties of vortices, we propose an analytical formula f
