Spontaneous Beliaev-Landau scattering out of equilibrium
Mathias Van Regemortel, Wim Casteels, Iacopo Carusotto +1
We investigate Beliaev-Landau scattering in a gas of interacting photons in a coherently driven array of nonlinear dissipative resonators, as described by the 1D driven-dissipative…
Optically bistable driven-dissipative Bose-Hubbard dimer: Gutzwiller approaches and entanglement
Wim Casteels, Michiel Wouters
We theoretically examine the driven-dissipative Bose-Hubbard dimer in the optical bistable regime. Various approximation schemes based on a Gutzwiller mean field decoupling are app…
On the robustness of strongly correlated multi-photon states in frustrated driven-dissipative cavity lattices
Riccardo Rota, Wim Casteels, Cristiano Ciuti
We present a theoretical study on the robustness of multi-photon states in a frustrated lattice of coupled nonlinear optical cavities, which are described by a driven-dissipative B…
Critical dynamical properties of a first-order dissipative phase transition
Wim Casteels, Rosario Fazio, Cristiano Ciuti
We theoretically investigate the critical properties of a single driven-dissipative nonlinear photon mode. In a well-defined thermodynamical limit of large excitation numbers, the…
Exact steady state of a Kerr resonator with one- and two-photon driving and dissipation: Controllable Wigner-function multimodality and dissipative phase transitions
Nicola Bartolo, Fabrizio Minganti, Wim Casteels +1
We present exact results for the steady-state density matrix of a general class of driven-dissipative systems consisting of a nonlinear Kerr resonator in the presence of both coher…
Quantum entanglement in the spatial symmetry breaking phase transition of a driven-dissipative Bose-Hubbard dimer
Wim Casteels, Cristiano Ciuti
We theoretically explore quantum correlation properties of a dissipative Bose-Hubbard dimer in presence of a coherent drive. In particular, we focus on the regime where the semicla…
Exact results for Schrödinger cats in driven-dissipative systems and their feedback control
F. Minganti, N. Bartolo, J. Lolli +2
In quantum optics, photonic Schrödinger cats are superpositions of two coherent states with opposite phases and with a significant number of photons. Recently, these states have be…
Power-laws in the dynamic hysteresis of quantum nonlinear photonic resonators
W. Casteels, F. Storme, A. Le Boité +1
We explore theoretically the physics of dynamic hysteresis for driven-dissipative nonlinear photonic resonators. In the regime where the semiclassical mean-field theory predicts bi…
