Stochastic resonance and heat fluctuations in a driven double-well system
Mamata Sahoo, Shantu Saikia, Mangal C. Mahato +1
We study a periodically driven (symmetric as well as asymmetric)double-well potential system at finite temperature. We show that mean heat loss by the system to the environment(bat…
Fluctuation theorems and orbital magnetism in nonequilibrium state
A. M. Jayannavar, Mamata Sahoo
We study Langevin dynamics of a driven charged particle in the presence as well as in the absence of magnetic field. We discuss the validity of various work fluctuation theorems us…
Supersymmetry and Fokker-Planck dynamics in periodic potentials
Mamata Sahoo, Mangal C. Mahato, A. M. Jayannavar
Recently, the Fokker-Planck dynamics of particles in periodic potentials , have been investigated by using the matrix continued fraction method. It was found that the two pe…
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…
