Spectral distribution of nonlinear oscillators with nonlinear friction due to a medium

TLDR
In this article, the analog of a quantum kinetic equation for the description of time correlation functions of singled out nonlinear oscillators interacting with a medium (e.g., local or quasi-local vibrations in crystals) is obtained.
Abstract
The analog of a quantum kinetic equation for the description of time correlation functions of singled out nonlinear oscillators interacting with a medium (e.g. local or quasi-local vibrations in crystals) is obtained. Both the frictions, the linear and nonlinear one (the latter is due to decays with participation of two quanta of singled out oscillators), were taken into account. Spectral distributions of the correlation functions of the coordinates are found as well as those of occupation numbers. The essentially non-Lorentzian shape of the spectral distribution and its dependence on interaction parameters and temperature are analysed. [Russian Text Ignored].

Quantum Synchronization of Quantum van der Pol Oscillators with Trapped Ions

TL;DR: In this article, the authors investigate how quantum fluctuations affect phase locking of one or many van der Pol oscillators and find that phase locking is much more robust in the quantum model than in the equivalent classical model.

Parametric amplification and self-oscillation in a nanotube mechanical resonator.

TL;DR: The corresponding damping rate is lower than the one obtained from the line shape of the resonance (without pumping), supporting the recently reported scenario that describes damping in nanotube resonators by a nonlinear force.

Brownian Motion of a Quantum Oscillator

TL;DR: In this paper, an action principle technique for the direct computation of expectation values is described and illustrated in detail by a special physical example, the effect on an oscillator of another physical system, which has the advantage of combining immediate physical applicability (e.g., resistive damping or maser amplification of a single electromagnetic cavity mode) with a significant idealization of the complex problems encountered in many particle and relativistic fieldtheory.
