Macroscopic fluctuation theory of stochastic systems undergoing monitoring
João Costa, Pedro Ribeiro, Andrea De Luca
We develop a macroscopic fluctuation theory for diffusive classical lattice gases subject to continuous coarse-grained monitoring. Treating measurements in the typical-outcome (que…

Nonlinear Fluctuating Hydrodynamics from Interacting Noisy Quantum Matter
Alexios Christopoulos, João Costa, Stefano Scopa +4
A universal characterization of non-equilibrium steady states in interacting quantum many-body systems remains one of the central challenges of statistical physics. Here, we addres…

Emergence of universality in transport of noisy free fermions
João Costa, Pedro Ribeiro, Andrea De Luca
We analyze the effects of various forms of noise on one-dimensional systems of non-interacting fermions. In the strong noise limit, we demonstrate, under mild assumptions, that the…
