Non-Hermitian entropy production from fluctuation theorems
Vasco Cavina, Frank Ernesto Quintela Rodríguez, Donato Farina
We develop a first-principles thermodynamic framework for non-Hermitian dynamics based on a post-selected version of the fluctuation theorem. This allows us to identify a quantity…

Exceptional points in Gaussian channels: diffusion gauging and drift-governed spectrum
Frank Ernesto Quintela Rodríguez
McDonald and Clerk [Phys.\ Rev.\ Research 5, 033107 (2023)] showed that for linear open quantum systems the Liouvillian spectrum is independent of the noise strength. We first make…
