Coherent stochastic resonance in one dimensional diffusion with one reflecting and one absorbing boundaries
Asish K. Dhara, Tapan Mukhopadhya
It is shown that the single-step periodic signal (periodic telegraph signal) can not produce coherent stochastic resonance for diffusion on a segment with one absorbing and one ref…

Synchronization under periodic modulation of potential wells in a two-state stochastic system
Asish K. Dhara, S. R. Banerjee
We analyse the effect of synchronization between noise and periodic signal in a two-state spatially extended system analytically. Resonance features are demonstrated. To have the m…

Asymptotic expansion in the fission process
Asish K. Dhara, Sailajananda Bhattacharya, Kewal Krishan Variable Energy Cyclotron Centre +2
Asymptotic expansion of the Fokker-Planck equation in terms of the strength of the fluctuation has been carried out. The mean and the variance of the total kinetic energies of the…
