Quasi-viscous accretion flow -- I: Equilibrium conditions and asymptotic behaviour
Jayanta K. Bhattacharjee, Atri Bhattacharya, Tapas K. Das +1
In a novel approach to studying viscous accretion flows, viscosity has been introduced as a perturbative effect, involving a first-order correction in the -viscosity parameter.…
Turing Patterns in two dimensional reaction-diffusion system: effect of an electric field
B K Agarwalla, J K Bhattacharjee, P Titum
We consider a two dimensional Turing like system with two diffusing species which interact with each other. Considering the species to be charged, we include the effect of an elect…
Is Turbulence as Simple as Tossing a Coin?
Jayanta Kumar Bhattacharjee, Sagar Chakraborty, Arnab Saha
A large variety of problems in statistical physics use a Gaussian distribution as a starting point. For the problem of intermittency in fluid turbulence, the Gaussian approximation…
Perturbative and non-perturbative studies with the delta function potential
Nabakumar Bera, Kamal Bhattacharyya, Jayanta K. Bhattacharjee
We show that the delta function potential can be exploited along with perturbation theory to yield the result of certain infinite series. The idea is that any exactly soluble poten…
Resonance and limit cycle in a noise driven Lorenz model
Himadri S. Samanta, J. K. Bhattacharjee
The effect of an external noise on the Lorenz model is investigated near the onset of convection and near the Hopf bifurcation. We show the existence of a diverging time scale near…
Critical Casimir force in the superfluid phase: effect of fluctuations
Shyamal Biswas, J. K. Bhattacharjee, Himadri S. Samanta +2
We have considered the critical Casimir force on a He film below and above the bulk point. We have explored the role of fluctuations around the mean field theory in a pertu…
