AC driven thermal ratchets
Debasis Dan, A. M. Jayannavar, Mangal C. Mahato
We consider the motion of a overdamped Brownian particle in periodic asymmetric potential with space dependent friction coefficient. In the presence of external time periodic forci…
Enhancement of mobility by periodically modulating the slanting slope of a washboard potential
Mangal C. Mahato, A. M. Jayannavar
Average mobility of very feebly damped particles in tilted periodic potentials is considered. Under the combined action of thermal fluctuations and small temporal modulation of the…
Macroscopic Equation of Motion in Inhomogeneous media
A. M. Jayannavar, Mangal C. Mahato
The dynamical evolution of a Brownian particle in an inhomogeneous medium with spatially varying friction and temperature field is important to understand conceptually. It requires…
Synchronized First-Passages in a Double-Well System
Mangal C. Mahato, A. M. Jayannavar
We perform Langevin dynamic numerical simulation on a double-well potential system subjected to an asymmetric saw-tooth type external time varying field and white noise forces. The…
