Motional dispersions and ratchet effect in inertial systems
W. L. Reenbohn, S. Saikia, R. Roy +1
We obtain ratchet effect in inertial structureless systems in symmetric periodic potentials where the asymmetry comes from the nonuniform friction offered by the medium and driven…
Work Fluctuations and Stochastic Resonance
Shantu Saikia, Ratnadeep Roy, A. M. Jayannavar
We study Brownian particle motion in a double-well potential driven by an ac force. This system exhibits the phenomenon of stochastic resonance. Distribution of work done on the sy…
Hysteresis in One-Dimensional Anti-Ferromagnetic Random-Field Ising Model at Zero-Temperature
Prabodh Shukla, Ratnadeep Roy, Emilia Ray
We analyse hysteresis in a one-dimensional anti-ferromagnetic random field Ising model at zero-temperature. The random field is taken to have a rectangular distribution of width $2…
Hysteretic Response of an Anti-Ferromagnetic Random-Field Ising Model in One Dimension at Zero Temperature
Prabodh Shukla, Ratnadeep Roy, Emilia Ray
We consider the hysteretic response of a one-dimensional anti-ferromagnetic random-field Ising model at zero temperature for a uniform bounded distribution of quenched random field…
