Diffusion-reaction approach to electronic relaxation in solution: Exact time domain solution for Dirac delta function sink model
Saravanan Rajendran, Aniruddha Chakraborty
We propose an analytical method for finding the time domain solution for the problem of electronic relaxation of a molecule in solution. The relaxation process is modeled by the de…
Exact dynamics of a Gaussian wave-packet in two potential curves coupled at a point
Saravanan Rajendran, Aniruddha Chakraborty
We present a method to calculate exact dynamics of a wave-packet in a quantum two-state problem with Dirac delta coupling. The advantage of our method is that the calculations are…
An exact analytical scheme using a new potential to solve one-dimensional quantum systems
Saravanan Rajendran, Deepak Kumar, Aniruddha Chakraborty
We propose an exact method for solving a one-dimensional Schrödinger equation. An arbitrary potential is represented by the collection of short-width potentials. For building the c…
Matter wave switching in Bose-Einstein condensates via intensity redistribution soliton interactions
S. Rajendran, P. Muruganandam, M. Lakshmanan
Using time dependent nonlinear (s-wave scattering length) coupling between the components of a weakly interacting two component Bose-Einstein condensate (BEC), we show the possibil…
Interaction of dark-bright solitons in two-component Bose-Einstein condensates
S. Rajendran, P. Muruganandam, M. Lakshmanan
We study the interaction of dark-bright solitons in two component Bose-Einstein condensates by suitably tailoring the trap potential, atomic scattering length and atom gain or loss…
Bright and dark solitons in a quasi 1D Bose-Einstein condensates modelled by 1D Gross-Pitaevskii equation with time-dependent parameters
S. Rajendran, P. Muruganandam, M. Lakshmanan
We investigate the exact bright and dark solitary wave solutions of an effective one dimensional (1D) Bose-Einstein condensate (BEC) by assuming that the interaction energy is much…
