Sample-specific rectification-like response in a boundary-driven exclusion process
Issei Sakai, Takuma Akimoto
We investigate the current response of a boundary-driven symmetric exclusion process with quenched site disorder. Hard-core particles hop symmetrically on a one-dimensional lattice…
Symmetry Breaking of Current Response in Disordered Exclusion Processes
Issei Sakai, Takuma Akimoto
The bias-reversal symmetry -- where reversing an external bias inverts the current without changing its magnitude -- is a hallmark of nonequilibrium transport. While this property…
Density-Independent transient caging in the high-density phase of motility-induced phase separation
Toranosuke Umemura, Issei Sakai, Takuma Akimoto
We investigate the nonequilibrium dynamics of active matter using a two-dimensional active Brownian particles model. In these systems, self-propelled particles undergo motility-ind…
Unexpected Effects of Disorder on Current Fluctuations in the Symmetric Simple Exclusion Process
Issei Sakai, Takuma Akimoto
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…
Non-self-averaging of current in a totally asymmetric simple exclusion process with quenched disorder
Issei Sakai, Takuma Akimoto
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 proper…
