Shiyi Wei - Fluctuations in noisy quantum diffusive systems out-of-equilibrum

Equilibrium statistical mechanics provides a general framework for characterizing many-body systems, while no comparably universal framework is known out of equilibrium. In this talk, I will present boundary-driven noisy quantum systems with diffusive transport. More specifically, I will consider the Quantum Symmetric Simple Exclusion and Inclusion Processes (QSSEP and QSSIP), solvable models describing fermionic and bosonic particles undergoing stochastic quantum hopping. I will focus on density and current fluctuations and their large-deviation statistics. A central theme is that these fluctuations exhibit classical behavior at leading macroscopic order, while genuinely quantum corrections survive beyond it. I will conclude by discussing possible connections to universal fluctuation phenomena in quantum transport.
