Self-tuning of threshold for a two-state system
Boyoung Seo, Raishma Krishnan, Toyonori Munakata
A two-state system (TSS) under time-periodic perturbations (to be regarded as input signals) is studied in connection with self-tuning (ST) of threshold and stochastic resonance (S…
Brownian motors: Joint effect of non-Gaussian noise and time asymmetric forcing
Raishma Krishnan, Horacio S. Wio
Previous works have shown that time asymmetric forcing on the one hand, as well as non-Gaussian noises on the other, can separately enhance the efficiency and current of a Brownian…
Reliability of fluctuation-induced transport in a Maxwell-demon-type engine
Raishma Krishnan, Sanjay Puri, Arun M. Jayannavar
We study the transport properties of an overdamped Brownian particle which is simultaneously in contact with two thermal baths. The first bath is modeled by an additive thermal noi…
Stoke's efficiency of temporally rocked ratchets
Raishma Krishnan, Jim Chacko, Mamata Sahoo +1
We study the generalized efficiency of an adiabatically rocked ratchet with both spatial and temporal asymmetry. We obtain an analytical expression for the generalized efficiency i…
Noise induced currents and reliability of transport in frictional ratchets
Raishma Krishnan, Debasis Dan, A. M. Jayannavar
We study the coherence of transport of an overdamped Brownian particle in frictional ratchet system in the presence of external Gaussian white noise fluctuations. The analytical ex…
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…
