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…

Parallel ergotropy: Maximum work extraction via parallel local unitary operations
Riccardo Castellano, Ranieri Nery, Kyrylo Simonov +1
Maximum quantum work extraction is generally defined in terms of the ergotropy functional, no matter how experimentally complicated is the implementation of the optimal unitary all…

Extended local ergotropy
Riccardo Castellano, Donato Farina, Vittorio Giovannetti +1
A fundamental problem in quantum thermodynamics is to properly quantify the work extractable from out-of-equilibrium systems. While for closed systems, maximum quantum work extract…
