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…
