Emergent equilibrium and quantum criticality in a two-photon dissipative oscillator

V. Yu. Mylnikov, S. O. Potashin, G. S. Sokolovskii +1

We study the dissipative phase transition in a quantum oscillator with two-photon drive and two-photon dissipation. Using the semi-classical Langevin equation and the Fokker-Plank…
