Magnetic field induced anomalous distribution of particles
Shrabani Mondal, L. R. Rahul Biswas, Mousumi Biswas +1
It seems that a stochastic system must be a nonlinear one to observe the phenomenon, noise induced transition. But in the present paper, we have demonstrated that the phenomenon ma…

Mechanism of barrier crossing dynamics in the presence of both time dependent and independent magnetic fields
Shrabani Mondal, Mousumi Biswas, Bidhan Chandra Bag
In this paper we have presented the mechanism of the barrier crossing dynamics of a Brownian particle which is coupled to a thermal bath in the presence of both time independent an…

A shortcut way to the Fokker-Planck equation for the non-Markovian dynamics
Joydip Das, Mousumi Biswas, Bidhan Chandra Bag
Using a shortcut way we have derived the Fokker-Planck equation for the Langevin dynamics with a generalized frictional memory kernel and time-dependent force field. Then we have s…
