Mean-field validity in a dissipative critical system: Liouvillian gap, -symmetric antigap, and permutational symmetry in the model
Dolf Huybrechts, Fabrizio Minganti, Franco Nori +2
We study the all-to-all connected (anisotropic-Heisenberg) spin model with local and collective dissipations, comparing the results of mean field theory with the solution of…
Dissipation-induced bistability in the two-photon Dicke model
Louis Garbe, Peregrine Wade, Fabrizio Minganti +3
The Dicke model is a paradigmatic quantum-optical model describing the interaction of a collection of two-level systems with a single bosonic mode. Effective implementations of thi…
Quantum and semiclassical exceptional points of a linear system of coupled cavities with losses and gain within the Scully-Lamb laser theory
Ievgen I. Arkhipov, Adam Miranowicz, Fabrizio Minganti +1
In the past few decades, many works have been devoted to the study of exceptional points (EPs), i.e., exotic degeneracies of non-Hermitian systems. The usual approach in those stud…
Quantum exceptional points of non-Hermitian Hamiltonians and Liouvillians: The effects of quantum jumps
Fabrizio Minganti, Adam Miranowicz, Ravindra W. Chhajlany +1
Exceptional points (EPs) correspond to degeneracies of open systems. These are attracting much interest in optics, optoelectronics, plasmonics, and condensed matter physics. In the…
