Brownian Motion - Past and Present
J. K. Bhattacharya, Dipanjan Chakraborty, Himadri Shekar Samanta
We discuss Brownian Motion from a more elementary viewpoint presented by Einstein in 1908. Later developments and applications are briefly reviewed.
Fokker-Planck Equation : Long-Time Dynamics in Approach to Equilibrium
Himadri S. Samanta, J. K. Bhattacharjee
We discuss the approach to equilibrium of systems governed by the Fokker-Planck equation. In particular, we focus on problems involving barrier penetration and the associated Krame…
Growth Models and Models of Turbulence : A Stochastic Quantization Perspective
Himadri S. Samanta, J. K. Bhattacharjee, D. Gangopadhyay
We consider a class of growth models and models of turbulence based on the randomly stirred fluid. The similarity between the predictions of these models, noted a decade earlier, i…
Non equilibrium statistical physics with fictitious time
Himadri S. Samanta, J. K. Bhattacharjee
Problems in non equilibrium statistical physics are characterized by the absence of a fluctuation dissipation theorem. The usual analytic route for treating these vast class of pro…
