Multilane Asymmetric Exclusion Process with stationary Bernoulli measure
Vladislav Popkov
We consider an Asymmetric Exclusion Process evolving on parallel mutually interacting lanes with neighbouring nearest hoppings of hardcore particles. Number of particles on each la…

Universality in driven systems with a multiply-degenerate umbilic point
Johannes Schmidt, Žiga Krajnik, Vladislav Popkov
We investigate a driven particle system, a multilane asymmetric exclusion process, where the particle number in every lane is conserved, and stationary state is fully uncorrelated.…

Universality in many-body driven systems with an umbilic point
Johannes Schmidt, Žiga Krajnik, Vladislav Popkov
We study stationary fluctuations of conserved slow modes in a two-lane model of hardcore particles which are expected to show universal behaviour. Specifically, we focus on the pro…
