Scaling behavior of a nonlinear oscillator with additive noise, white and colored
K. Mallick, P. Marcq
We study analytically and numerically the problem of a nonlinear mechanical oscillator with additive noise in the absence of damping. We show that the amplitude, the velocity and t…

Anomalous diffusion in nonlinear oscillators with multiplicative noise
Kirone Mallick, Philippe Marcq
The time-asymptotic behavior of undamped, nonlinear oscillators with a random frequency is investigated analytically and numerically. We find that averaged quantities of physical i…
