Enhanced thermodynamic efficiency in time asymmetric ratchets
Raishma Krishnan, Soumen Roy, A. M. Jayannavar
The energetic efficiency of an overdamped Brownian particle in a saw tooth potential in the presence of time asymmetric forcing is studied in the adiabatic limit. An error made in…
Diffusion accompanying noise induced transport in frictional ratchets
Raishma Krishnan, Debasis Dan, A. M. Jayannavar
We study the noise induced transport of an overdamped Brownian particle in frictional ratchet systems in the presence of external Gaussian white noise fluctuations. The analytical…
Bona fide Stochastic Resonance: A view point from stochastic energetics
Debasis Dan, A. M. Jayannavar
We investigate the resonance type behaviour of an overdamped Brownian particle in a bistable potential driven by external periodic signal. It has been shown previously that the inp…
Inhomogeneous Systems and their Rectification Properties
A. M. Jayannavar
We explore the possibility of obtaining unidirectional current in a symmetric (periodic) potential system without the application of any obvious (apparent) externally applied bias.…
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…
