Temporally correlated zero-range process with open boundaries: Steady state and fluctuations

Abstract: We study an open-boundary version of the on-off zero-range process introduced in Hirschberg et al. [Phys. Rev. Lett. 103, 090602 (2009)]. This model includes temporal correlations which can promote the condensation of particles, a situation observed in real-world dynamics. We derive the exact solution for the steady state of the one-site system, as well as a mean-field approximation for larger one-dimensional lattices, and also explore the large deviation properties of the particle current. Analytical and nume… Show more

“…where, for our model with α(j) = α 0 + aj, the fixed point j * is given by (15). Now, as argued in section 3, we expect long-time diffusive behaviour with modified diffusion coefficient D * /(1 − 2A * ) when A * of (16) is less than 1/2.…”

“…Much less is known about non-Markovian many-particle systems but some aspects of the stationary-state properties (e.g., mean current as a function of density, conditions for a condensation transition) have been investigated for models with internal states or non-exponential waiting times [12,13,14]. Going beyond the typical behaviour, the current fluctuations in a temporally-correlated zero-range process have also recently been explored (and compared to the equivalent memoryless model) although exact analytical calculations proved possible only for a single site [15].…”

“…We also mention that, in the recent literature, ZRP with modified blockage rules have also been studied in different frameworks, e.g. non-Markovian processes and traffic models [20,21,22,23]. This model can be thought of as a basic model for pedestrians on a lane with a width shrinkage due to a corridor or a door.…”

“…Related results have been also proved in [7]. It is also worth mentioning that in the recent literature, in different framework as non-Markovian process and traffic models, ZRP with modified blockage rules have been considered [8][9][10][11].…”
