Unexpected Effects of Disorder on Current Fluctuations in the Symmetric Simple Exclusion Process

We explore how the disorder impacts the current fluctuations in the symmetric simple exclusion process (SSEP) within a heterogeneous environment. First, we analyze the SSEP with a defect site under the periodic boundary conditions. We derive the exac

Sample-to-sample fluctuations of transport coefficients in the totally asymmetric simple exclusion process with quenched disorder

Autor: Sakai, Issei, Akimoto, Takuma

Publikováno v: Phys. Rev. E 107, 054131 (2023)

We consider the totally asymmetric simple exclusion processes on quenched random energy landscapes. We show that the current and the diffusion coefficient differ from those for homogeneous environments. Using the mean-field approximation, we analytic

Non-self-averaging of current in a totally asymmetric simple exclusion process with quenched disorder

Autor: Sakai, Issei, Akimoto, Takuma

Publikováno v: Phys. Rev. E 107, L052103 (2023)

We investigate the current properties in the totally asymmetric simple exclusion process (TASEP) on a quenched random energy landscape. In low- and high-density regimes, the properties are characterized by single-particle dynamics. In the intermediat
