Non-Hermitian entropy production from fluctuation theorems
Vasco Cavina, Frank Ernesto Quintela RodrÃguez, 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 RodrÃguez
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…
Quantum dynamics in the self-consistent quadratic approximation
Frank Ernesto Quintela Rodriguez
A self-consistent quadratic theory is presented to account for nonlinear contributions in quantum dynamics. Evolution equations are shown to depend on higher-order gradients of the…
Quantum Dynamics of Dissipative Polarizable Media
Frank Ernesto Quintela Rodriguez, Piero Lafiosca, Tommaso Giovannini +1
Classical polarizable approaches have become the gold standard for simulating complex systems and processes in the condensed phase. These methods describe intrinsically dissipative…
Extracting energy via bosonic Gaussian operations
Frank Ernesto Quintela Rodriguez, Francesco Anna Mele, Salvatore Francesco Emanuele Oliviero +3
Quantum thermodynamics is often formulated as a theory with constrained access to operations and resources. In this manuscript, we find a closed formula for the Gaussian ergotropy,…
