Title: From Kardar-Parisi-Zhang scaling to soliton proliferation in Josephson junction arrays

Speaker: Mikheil Tsitsishvili, Heinrich Heine University, Düsseldorf, Germany

Abstract: 

The Kardar-Parisi-Zhang (KPZ) universality class plays a central role in nonequilibrium statistical physics, encompassing scaling phenomena ranging from bacterial colony growth to driven-dissipative Bose condensates. Despite its ubiquity, the number of controllable experimental platforms where KPZ scaling can be explored remains limited. In this talk we will argue that the Josephson junction arrays can be a realistic platform for observing non-equilibrium scaling laws characterized by the KPZ universality class, and space-time soliton proliferation. Before diving into the results regarding the proposed experimental setup, we will very briefly review some aspects of the Josephson systems, KPZ physics and soliton activation problem.

The talk will mainly cover the content of the following preprint https://arxiv.org/abs/2509.08479
