Homodyne versus photon-counting quantum trajectories for dissipative Kerr resonators with two-photon driving
Nicola Bartolo, Fabrizio Minganti, Jared Lolli +1
We investigate two different kinds of quantum trajectories for a nonlinear photon resonator subject to two-photon pumping, a configuration recently studied for the generation of ph…
Critical behavior of dissipative two-dimensional spin lattices
R. Rota, F. Storme, N. Bartolo +2
We explore critical properties of two-dimensional lattices of spins interacting via an anisotropic Heisenberg Hamiltonian and subject to incoherent spin flips. We determine the ste…
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…
Nonequilibrium Casimir-Polder plasmonic interactions
Nicola Bartolo, Riccardo Messina, Diego A. R. Dalvit +1
We investigate how the combination of nonequilibrium effects and material properties impacts on the Casimir-Polder interaction between an atom and a surface. By addressing systems…
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…
