Slow quench dynamics in classical systems: kinetic Ising model and zero-range process
Priyanka, Sayani Chatterjee, Kavita Jain
While a large number of studies have focused on the nonequilibrium dynamics of a system when it is quenched instantaneously from a disordered phase to an ordered phase, such dynami…
Hydrodynamics, density fluctuations and universality in conserved stochastic sandpiles
Sayani Chatterjee, Arghya Das, Punyabrata Pradhan
We study conserved stochastic sandpiles (CSSs), which exhibit an active-absorbing phase transition upon tuning density . We demonstrate that a broad class of CSSs possesses a re…
Spatial correlations, additivity and fluctuations in conserved-mass transport processes
Arghya Das, Sayani Chatterjee, Punyabrata Pradhan
We exactly calculate two-point spatial correlation functions in steady state in a broad class of conserved-mass transport processes, which are governed by chipping, diffusion and c…
Additivity property and emergence of power laws in nonequilibrium steady states
Arghya Das, Sayani Chatterjee, Punyabrata Pradhan +1
We show that an equilibriumlike additivity property can remarkably lead to power-law distributions observed frequently in a wide class of out-of-equilibrium systems. The additivity…
Zeroth law of thermodynamics for nonequilibrium steady states in contact
Sayani Chatterjee, Punyabrata Pradhan, P. K. Mohanty
We ask what happens when two systems having a nonequilibrium steady state are kept in contact and allowed to exchange a quantity, say mass, which is conserved in the combined syste…
Gammalike mass distributions and mass fluctuations in conserved-mass transport processes
Sayani Chatterjee, Punyabrata Pradhan, P. K. Mohanty
We show that, in conserved-mass transport processes, the steady-state distribution of mass in a subsystem is uniquely determined from the functional dependence of variance of the s…
