Stationary densities and delocalized domain walls in asymmetric exclusion processes competing for finite pools of resources
Sourav Pal, Parna Roy, Abhik Basu
We explore the stationary densities and domain walls in the steady states of a pair of asymmetric exclusion processes (TASEP) antiparallelly coupled to two particle reservoirs with…
Availability versus carrying capacity: Phases of asymmetric exclusion processes competing for finite pools of resources
Astik Haldar, Parna Roy, Erwin Frey +1
We address how the interplay between the finite availability and carrying capacity of particles at different parts of a spatially extended system can control the steady state curre…
Distributed fixed resources exchanging particles: Phases of an asymmetric exclusion process connected to two reservoirs
Sourav Pal, Parna Roy, Abhik Basu
We propose and study a conceptual one-dimensional model to explore how the combined interplay between fixed resources and particle exchanges between different parts of an extended…
Availability, storage capacity, and diffusion: Stationary states of an asymmetric exclusion process connected to two reservoirs
Sourav Pal, Parna Roy, Abhik Basu
We explore how the interplay of finite availability, carrying capacity of particles at different parts of a spatially extended system and particle diffusion between them control th…
Asymmetric exclusion processes with fixed resources: Reservoir crowding and steady states
Astik Haldar, Parna Roy, Abhik Basu
We study the nonequilibrium steady states of an asymmetric exclusion process (TASEP) coupled to a reservoir of unlimited capacity. We elucidate how the steady states are controlled…
Pinned or moving: states of a single shock in a ring
Parna Roy, Anjan Kumar Chandra, Abhik Basu
Totally asymmetric exclusion processes (TASEP) with open boundaries are known to exhibit moving shocks or delocalised domain walls (DDW) for sufficiently small equal injection and…
Interplay of interfacial noise and curvature driven dynamics in two dimensions
Parna Roy, Parongama Sen
We explore the effect of interplay of interfacial noise and curvature driven dynamics in a binary spin system. An appropriate model is the generalised two dimensional voter model p…
Continuous utility factor in segregation models
Parna Roy, Parongama Sen
We consider the constrained Schelling model of social segregation in which the utility factor of agents strictly increases and non-local jumps of the agents are allowed. In the pre…
Exit Probability in Generalised Kinetic Ising Model
Parna Roy, Parongama Sen
In this paper we study generalised Ising Glauber models with inflow of informa- tion in one dimension and derive expressions for the exit probability using well established analyti…
Universal features of exit probability in opinion dynamics models with domain size dependent dynamics
Parna Roy, Soham Biswas, Parongama Sen
We study the exit probability for several binary opinion dynamics models in one dimension in which the opinion state (represented by ) of an agent is determined by dynamical…
Exit probability in inflow dynamics: nonuniversality induced by range, asymmetry and fluctuation
Parna Roy, Soham Biswas, Parongama Sen
Probing deeper into the existing issues regarding the exit probability (EP) in one dimensional dynamical models, we consider several models where the states are represented by Isin…
