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…

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,…

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…
