“…However, as it was shown in Refs. [22] and [23], a superradiance pulse can also arise in a classical system of nonlinear oscillators coupled to the cavity field due to rephasing processes. In terms of new variables the dimensionless Hamiltonian is given by H = (α/∆ 2 )H eff :…”

Bistability of a nonlinear resonantly-driven oscillator in the presence of external noise is analyzed using the classical Fokker-Planck equation in the quasienergy space with account for tunneling effects and by quantum master equation in quasienergy states representation. Two timescales responsible for different stages of this bistable system relaxation have been obtained. We found that the slow relaxation rate caused by fluctuation-induced transitions between different stable states can be enhanced by several orders of magnitude due to the tunneling effects. It was also revealed that tunneling between nearly degenerate quasienergy states and resonant multiphoton transitions between the genuine eigenstates of the nonlinear oscillator are just the similar effects. It was demonstrated that the quasienergy states in the bistability region corresponding to higher amplitude are squeezed. The degree of squeezing is determined by the ratio between nonlinearity and detuning, so that the uncertainty of one quadrature can be considerably smaller than the quantum limit. We found that tunneling effects can enhance the generation of output oscillator squeezed states. It was demonstrated that 1D Fokker-Planck equation is a quasiclassical limit of a quantum master equation.arXiv:1901.05243v2 [cond-mat.mes-hall]

“…Since then, the Dicke superradiance (SR) has brought a tremendous attention to the quantum optics community [2,3,4,5,6,7,9,10,11,12,13,14,15] . However, the recent experimental realizations of the complex quantum systems of strongly correlated many bodies in gas, liquid and solid-state phases [16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33] demand the understanding of collective phenomena in much broader sense [34,35,36,37]. For example, the surprisingly tolerant superfluorescence (SF) has been recently demonstrated in perovskite materials at room temperature [31,32], which may be understood by a quantum analog of vibration isolation mechanism [37].…”
