Abstracts
Abstracts
In this talk, we demonstrate Kardar-Parisi-Zhang and Edwards-Wilkinson (EW) universality in two integrable interacting particle systems on a periodic lattice: the q-boson Zero-Range Process (ZRP) and Asymmetric Avalanche Process (AAP). The q-boson ZRP exhibits KPZ scaling (|q| ≠ 1) with α=1/3, β=2/3 roughness/growth exponents and EW scaling (at q=1) with α=1/4, β=1/2; the AAP displays KPZ behavior below critical density ρ_c. We extract these KPZ/EW exponents and crossover scaling functions from the KPZ equation, matching them precisely to asymptotics of the models' height functions derived via Bethe ansatz and TQ-equations. Integrability provides exact cumulants and universal forms, such as crossover functions aligning with those for an asymmetric simple exclusion process (ASEP).
The talk is based on A A Trofimova and A M Povolotsky 2022 J. Phys. A: Math. Theor. 55 025202 and A A Trofimova and A M Povolotsky 2020 J. Phys. A: Math. Theor. 53 365203 and ongoing research.
