Emergent equilibrium and quantum criticality in a two-photon dissipative oscillator
We study the dissipative phase transition (DPT) in a quantum oscillator with two-photon drive and two-photon dissipation. Using the semiclassical Langevin equation and the truncated Wigner approximation, we construct a theory of nonperturbative quantum fluctuations and go beyond the semiclassical ap...
