Can the macroscopic fluctuation theory be quantized?

D Bernard - Journal of Physics A: Mathematical and Theoretical, 2021 - iopscience.iop.org
The macroscopic fluctuation theory (MFT) is an effective framework to describe transports

Liouvillian skin effects and fragmented condensates in an integrable dissipative Bose-Hubbard model

C Ekman, EJ Bergholtz - Physical Review Research, 2024 - APS
Strongly interacting nonequilibrium systems are of great fundamental interest, yet their
inherent complexity make them notoriously hard to analyze. We demonstrate that the …
