Super-Critical and Sub-Critical Hopf bifurcations in two and three dimensions
Debapriya Das, Dhruba Banerjee, Jayanta K. Bhattacharjee
Hopf bifurcations have been studied perturbatively under two broad headings, viz., super-critical and sub-critical. The criteria for occurrences of such bifurcations have been inve…
Ground state of the one dimensional Gross-Pitaevskii equation with a Morse potential
Sukla Pal, Jayanta K. Bhattacharjee
We have studied the ground state of the Gross-Pitaevskii equation (nonlinear Schrodinger equation) for a Morse potential via a variational approach. It is seen that the ground stat…
Wave-packet dynamics for a coupled Gross-Pitaevskii equation
Sukla Pal, Jayanta K. Bhattacharjee
Starting from coupled Gross-Pitaevskii equation (GPE) describing the dynamics of binary Bose Einstein Condensate (BEC), we have explored the dynamics of the width of initial wave-p…
Acoustic horizons in nuclear fluids
Niladri Sarkar, Abhik Basu, Jayanta K. Bhattacharjee +1
We consider a hydrodynamic description of the spherically symmetric outward flow of nuclear matter, accommodating dispersion in it as a very weak effect. About the resulting statio…
Stability analysis of fluid flows using Lagrangian Perturbation Theory (LPT): application to the plane Couette flow
Sharvari Nadkarni-Ghosh, Jayanta K. Bhattacharjee
We present a new application of Lagrangian Perturbation Theory (LPT): the stability analysis of fluid flows. As a test case that demonstrates the framework we focus on the plane Co…
Dynamical Structure Factor of Fulde-Ferrell-Larkin-Ovchinnikov Superconductors
Arghya Dutta, Jayanta K. Bhattacharjee
Superconductor with a spatially-modulated order parameter is known as Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconductor. Using the time-dependent Ginzburg-Landau (TDGL) formal…
