Particle dynamics and Stochastic Resonance in Periodic potentials
Shantu Saikia
We have studied the dynamics of a particle in a periodically driven underdamped periodic potential. Recent studies have reported the occurrence of Stochastic Resonance (SR) in such…
Ratchet effect in an underdamped periodic potential and its characterisation
Shantu Saikia
Ratchet effect in a driven underdamped periodic potential system is studied. The presence of a space dependent and periodic friction coefficient, but with a phase difference with t…
Stochastic Resonance in Periodic Potentials
S. Saikia, A. M. Jayannavar, Mangal C. Mahato
The phenomenon of stochastic resonance (SR) is known to occur mostly in bistable systems. However, the question of occurrence of SR in periodic potential systems is not conclusivel…
Deterministic inhomogeneous inertia ratchets
Shantu Saikia, Mangal C. Mahato
We study the deterministic dynamics of a periodically driven particle in the underdamped case in a spatially symmetric periodic potential. The system is subjected to a space-depend…
Dispersionless motion in a driven periodic potential
S. Saikia, Mangal C. Mahato
Recently, dispersionless (coherent) motion of (noninteracting) massive Brownian particles, at intermediate time scales, was reported in a sinusoidal potential with a constant tilt.…
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…
