Finding the optimum activation energy in DNA breathing dynamics: A Simulated Annealing approach
Pinaki Chaudhury, Ralf Metzler, Suman K Banik
We demonstrate how the stochastic global optimization scheme of Simulated Annealing can be used to evaluate optimum parameters in the problem of DNA breathing dynamics. The breathi…
Simple model for transport phenomena : Microscopic construction of Maxwell Demon like engine
Jyotipratim Ray Chaudhuri, Sudip Chattopadhyay, Suman Kumar Banik
We present a microscopic Hamiltonian framework to develop Maxwell demon like engine. Our model consists of a equilibrium thermal bath and a non-equilibrium bath; latter generated b…
Directed motion generated by heat bath nonlinearly driven by external noise
Jyotipratim Ray Chaudhuri, Debashis Barik, Suman Kumar Banik
Based on the system heat bath approach where the bath is nonlinearly modulated by an external Gaussian random force, we propose a new microscopic model to study directed motion in…
Nonequilibrium fluctuation induced escape from a metastable state
J. Ray Chaudhuri, D. Barik, S. K. Banik
Based on a simple microscopic model where the bath is in a non-equilibrium state we study the escape from a metastable state in the over-damped limit. Making use of Fokker-Planck-S…
Dynamics of a metastable state nonlinearly coupled to a heat bath driven by an external noise
Jyotipratim Ray Chaudhuri, Debashis Barik, Suman Kumar Banik
Based on a system-reservoir model, where the system is nonlinearly coupled to a heat bath and the heat bath is modulated by an external stationary Gaussian noise, we derive the gen…
Quantum phase space function formulation of reactive flux theory
Debashis Barik, Suman Kumar Banik, Deb Shankar Ray
On the basis of a coherent state representation of quantum noise operator and an ensemble averaging procedure a scheme for quantum Brownian motion has been proposed recently [Baner…
