Stochastic Quantisation and Non-Equilibrium Statistical Mechanics
Jayanta K. Bhattacharjee, Debashis Gangopadhyay
The stochastic quantisation technique of Parisi and Wu is extended to study non-equilibrium statistical mechanics. We show that this scheme is capable of handling white as well as…
Wavelength Doulbing Bifurcations In A Reaction Diffusion System
Deepak Kar, J K Bhattacharjee
In a two species reaction diffusion system,we show that it is possible to generate a set of wavelength doubling bifuractions leading to spatially chaotic state.The wavelength doubl…
ESS and Dissipation Range Dynamics of 3-D Turbulence
Anirban Sain, J. K. Bhattacharjee
We carry out a self consistent calculation of the structure functions in the dissipation range using Navier Stokes equation. Combining these results with the known structures in th…
Ultrasonic attenuation in d-wave superconductors
Vladimir N. Kostur, Jayanta K. Bhattacharjee, Richard A. Ferrell
The longitudinal ultrasonic attenuation at low temperatures for a -wave superconducting order parameter is examined. The ratio of the superconducting to normal state attenuation…
