Название: Resonant Response of a Thermalized Ensemble of Nonlinear Oscillators
Автор: Gerasimov A.
Journal of Statistical Physics, Vol. 70, No. 3/4, 1993. p. 939-948.
The analysis is carried out of the response of the center of gravity (dipole moment) of the distribution of noninteracting thermalized nonlinear oscillators to a sinusoidal driving force. Heat bath coupling is modeled by damping and noise. The driving is weak, but the frequency is resonant, so that there is a nonlinear resonance in the phase space. The response has a linear part that can be obtained from the perturbation analysis and a small nonlinear correction that is specific for the resonant structure.
