Driven tracers in a one-dimensional periodic hard-core lattice gas
@article{Lobaskin2020DrivenTI, title={Driven tracers in a one-dimensional periodic hard-core lattice gas}, author={Ivan Lobaskin and Martin R. Evans}, journal={Journal of Statistical Mechanics: Theory and Experiment}, year={2020}, volume={2020} }
Totally asymmetric tracer particles in an environment of symmetric hard-core particles on a ring are studied. Stationary state properties, including the environment density profile and tracer velocity are derived explicitly for a single tracer. Systems with more than one tracer are shown to factorise into single-tracer subsystems, allowing the single tracer results to be extended to an arbitrary number of tracers. We demonstrate the existence of a cooperative effect, where many tracers move…

Attraction and condensation of driven tracers in a narrow channel.

The mean-field approximation is applied to analytically explore the mechanism responsible for the tracers' emergent interactions and compute the resulting effective attractive potential, which is then numerically shown to extend to a realistic model of hard driven Brownian disks confined to a narrow 2D channel.
Cumulant generating functions of a tracer in quenched dense symmetric exclusion processes.

The cumulant generating function in the quenched case was only determined in the low-density limit and for the specific case of a half-filled system and here, it is derived in the opposite dense limit with quenches initial conditions.
