A numerical method for generation of quantum noise and solution of generalized c-number quantum Langevin equation
Dhruba Banerjee, Bidhan Chandra Bag, Suman Kumar Banik +1
Based on a coherent state representation of noise operator and an ensemble averaging procedure we have recently developed [Phys. Rev. E {\bf 65}, 021109 (2002); {\it ibid.} 051106…
Solutions of Fisher and Burger's equations with finite transport memory
Sandip Kar, Suman Kumar Banik, Deb Shankar Ray
The Fisher and Burgers' equations with finite memory transport, describing reaction-diffusion and convection-diffusion processes, respectively have recently attracted a lot of atte…
Correlated noise induced control of prey extinction
Suman Kumar Banik
We study the steady state properties of a phenomenological two-state predator model in presence of correlated Gaussian white noise. Based on the corresponding Fokker-Planck equatio…
The generalized Kramers' theory for an external noise driven bath
Jyotipratim Ray Chaudhuri, Suman Kumar Banik, Deb Shankar Ray
We consider a system-reservoir model where the reservoir is modulated by an external noise. Both the internal noise of the reservoir and the external noise are stationary, Gaussian…
Barrier crossing induced by very slow external noise
Suman Kumar Banik, Jyotipratim Ray Chaudhuri, Deb Shankar Ray
We consider the motion of a particle in a force field subjected to adiabatic, fluctuations of external origin. We do not put the restriction on the type of stochastic process that…
Adiabatic noise-induced escape rate for nonequilibrium open systems
Suman Kumar Banik, Jyotipratim Ray Chaudhuri, Deb Shankar Ray
We consider the motion of an overdamped particle in a force field in presence of an external, adiabatic noise, without the restriction that the noise process is Gaussian or the sto…
