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…
Looping of a long chain polymer in solution: Simple derivation for exact solution for a delta function sink
Moumita Ganguly, Aniruddha Chakraborty
A simple analytical method for solving intra-molecular reactions of polymer chain in dilute solution is formulated. The physical problem of looping can be modeled mathematically wi…
Diffusion on a flat potential with a new localized sink: Exact Analytical Solution
Hemani Chhabra, Aniruddha Chakraborty
We give a method for finding the exact analytical solution for the problem of a particle undergoing diffusive motion in a flat potential in the presence of a new localized sink. Th…
Theory of Electronic relaxation in solution: Exact solution in case of parabolic potential with a sink of finite width
Swati Mudra, Hemani Chhabra, Aniruddha Chakraborty
We give a general method for finding the exact solution for the problem of electronic relaxation in solution, modeled by a particle undergoing diffusive motion under a potential in…
Understanding dynamics of looping of a long chain polymer in solution: Wilemski-Fixman Approach
Moumita Ganguly, Aniruddha Chakraborty
We investigate theoretically the end-to-end looping time of a long chain polymer molecule immersed in a solvent. The dynamics of the end-to-end distance is governed by a Smoluchows…
