Directed motion generated by heat bath nonlinearly driven by external noise
Jyotipratim Ray Chaudhuri, Debashis Barik, Suman Kumar Banik
Based on the system heat bath approach where the bath is nonlinearly modulated by an external Gaussian random force, we propose a new microscopic model to study directed motion in…
Nonequilibrium fluctuation induced escape from a metastable state
J. Ray Chaudhuri, D. Barik, S. K. Banik
Based on a simple microscopic model where the bath is in a non-equilibrium state we study the escape from a metastable state in the over-damped limit. Making use of Fokker-Planck-S…
Dynamics of a metastable state nonlinearly coupled to a heat bath driven by an external noise
Jyotipratim Ray Chaudhuri, Debashis Barik, Suman Kumar Banik
Based on a system-reservoir model, where the system is nonlinearly coupled to a heat bath and the heat bath is modulated by an external stationary Gaussian noise, we derive the gen…
Inhomogeneous quantum diffusion and decay of a meta-stable state
Pulak Kumar Ghosh, Debashis Barik, Deb Shankar Ray
We consider the quantum stochastic dynamics of a system whose interaction with the reservoir is considered to be linear in bath co-ordinates but nonlinear in system co-ordinates. T…
Escape rate from a metastable state weakly interacting with a heat bath driven by an external noise
Jyotipratim Ray Chaudhuri, Debashis Barik, Suman Kumar Banik
Based on a system-reservoir model, where the reservoir is driven by an external stationary, Gaussian noise with arbitrary decaying correlation function, we study the escape rate fr…
Langevin dynamics with dichotomous noise; direct simulation and applications
Debashis Barik, Pulak Kumar Ghosh, Deb Shankar Ray
We consider the motion of a Brownian particle moving in a potential field and driven by dichotomous noise with exponential correlation. Traditionally, the analytic as well as the n…
