Diffusion Enhancement in a Periodic Potential under High-Frequency Space-Dependent Forcing
Malay Bandyopadhyay, Sushanta Dattagupta, Monamie Sanyal
We study the long-time behavior of underdamped Brownian particle moving through a viscous medium and in a systematic potential, when it is subjected to a space-dependent high-frequ…
Dissipative Tunneling in 2 DEG: Effect of Magnetic Field, Impurity and Temperature
Malay Bandyopadhyay
We have studied the transport process in the two dimensional electron gas (2DEG) in presence of a magnetic field and a dissipative environment at temperature T. By means of imagina…
"Stochastic Modeling of Coercivity " - A Measure of Non-equilibrium State
S. Chakraverty, M. Bandyopadhyay
A typical coercivity versus particle size curve for magnetic nanoparticles has been explained by using the Gilbert equation followed by the corresponding Fokker Plank equation. Kra…
Dissipative Diamagnetism -- A Case Study for Equilibrium and Nonequilibrium Statistical Mechanics of Mesoscopic Systems
Malay Bandyopadhyay, Sushanta Dattagupta
Using the path integral approach to equilibrium statistical physics the effect of dissipation on Landau diamagnetism is calculated. The calculation clarifies the essential role of…
