Asymmetric exclusion processes with constrained dynamics

TL;DR

This paper introduces asymmetric exclusion processes with local constraints to study how non-conservative forces influence athermal systems, revealing complex behaviors like rheology, negative resistance, and jamming.

Contribution

It presents a novel model incorporating local kinetic constraints in asymmetric exclusion processes to explore non-conservative driving effects in athermal systems.

Findings

Exhibits rheological-like behavior at high density

Shows negative differential resistance

Displays two-step relaxation and dynamical heterogeneity

Abstract

Asymmetric exclusion processes with locally reversible kinetic constraints are introduced to investigate the effect of non-conservative driving forces in athermal systems. At high density they generally exhibit rheological-like behavior, negative differential resistance, two-step structural relaxation, dynamical heterogeneity and, possibly, a jamming transition driven by the external field.
