Persistence of a Brownian particle in a Time Dependent Potential
D. Chakraborty
We investigate the persistence probability of a Brownian particle in a harmonic potential, which decays to zero at long times -- leading to an unbounded motion of the Brownian part…
Velocity autocorrelation function of a Brownian particle
D. Chakraborty
In this article, we present molecular dynamics study of the velocity autocorrelation function (VACF) of a Brownian particle. We compare the results of the simulation with the exact…
Persistence in Random Walk in Composite Media
D. Chakraborty
We consider a class of inhomogeneous media known as composite media that is often encountered in experimental sciences and investigate the persistence probability of a random walke…
Finite Size Effect in Persistence
D. Chakraborty, J. K. Bhattacharjee
We have investigated the random walk problem in a finite system and studied the crossover induced in the the persistence probability scales by the system size.Analytical and numeri…
