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…
