Transition time estimation for -function coupling in two state problem: An analytically solvable model
Mayank Vashistha, Chinmoy Samanta, Aniruddha Chakraborty
We propose a simple method to calculate transition time in a two-state scattering problem, where two constant potentials are coupled by a delta function potential $V_{12}=V_{21}=k_…
Understanding correlation between two bound state electrons using a simple model
Shivani Verma, Aniruddha Chakraborty
Understanding electron correlation requires solving inseparable Schrodinger equation. In general, inseparable Schrödinger equations cannot be solved analytically. So their solution…
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…
Exact results on diffusion in a piecewise linear potential with a time dependent sink
Diwaker, Anirudhha Chakraborty
The Smoluchowski equation with a time dependent sink term is solved exactly. In this method by knowing the probability distribution at the origin P(0,s), one may derive the probabi…
Multi-channel scattering problems: Analytical approach for exact solution using Green's functions
Diwaker, Aniruddha Chakraborty
We have proposed an analytical approach for exact solution of multi-channel scattering problems, in presence of Dirac Delta function couplings. Our solution is quite general and is…
