Diffusive-to-Ballistic transition in a Persistent Random Walk
Amit Pradhan, Reshmi Roy, Purusattam Ray
We study persistent random walk with time dependent velocity reversal probabilities and identify a criterion for a non-equilibrium dynamical transition. As a representative example…
Effect of presence of rigid impurities in a system of annihilating domain walls with dynamic bias
Reshmi Roy, Parongama Sen
The dynamics of interacting domain walls, regarded as a system of particles which are biased to move towards their nearest neighbours and annihilate when they meet, have been studi…
Queues with resetting: a perspective
Reshmi Roy, Arup Biswas, Arnab Pal
Performance modeling is a key issue in queuing theory and operation research. It is well-known that the length of a queue that awaits service or the time spent by a job in a queue…
Non-equilibrium dynamics in Ising like models with biased initial condition
Reshmi Roy, Parongama Sen
We investigate the dynamical fixed points of the zero temperature Glauber dynamics in Ising-like models. The stability analysis of the fixed points in the mean field calculation sh…
system in one dimension with particle motion determined by nearest neighbour distances: results for parallel updates
Reshmi Roy, Parongama Sen, Purusattam Ray
A one dimensional system where the direction of motion of the particles is determined by the position of the nearest neighours is studied. The particles move wi…
reaction for particles with a dynamic bias to move away from their nearest neighbour in one dimension
Reshmi Roy, Parongama Sen
We consider the dynamics of particles undergoing the reaction in one dimension with a dynamic bias. Here the particles move towards their nearest neighbour with…
Tagged particle dynamics in one dimensional models with the particles biased to diffuse towards their nearest neighbour
Reshmi Roy, Purusattam Ray, Parongama Sen
Dynamical features of tagged particles are studied in a one dimensional system for and 1, where the particles have a bias to…
