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…
Phase delay time and superluminal propagation in barrier tunneling
Swarnali Bandopadhyay, A. M. Jayannavar
In this work we study the behaviour of Wigner phase delay time for tunneling in the reflection mode. Our system consists of a circular loop connected to a single wire of semi-infin…
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…
Engines at molecular scales
Raishma Krishnan, A. M. Jayannavar
In recent literature there has been a lot of interest in the phenomena of noise induced transport in the absence of an average bias occurring in spatially periodic systems far from…
Equilibrium currents in quantum double ring system: A non-trivial role of system-reservoir coupling
Colin Benjamin, A. M. Jayannavar
Amperes law states that the magnetic moment of a ring is given by current times the area enclosed. Also from equilibrium statistical mechanics it is known that magnetic moment is t…
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…
