An Information-Theoretic Bound on Thermodynamic Efficiency and the Generalized Carnot's Theorem
Anna Gabetti, Fabrizio Dolcini, Davide Girolami
We derive a bound on the efficiency of thermal engines that can be sharper than Carnot's limit. It is a function of statistical correlations between the engine internal state and H…

Space and time correlations in quantum histories
Leonardo Castellani, Anna Gabetti
The formalism of generalized quantum histories allows a symmetrical treatment of space and time correlations, by taking different traces of the same history density matrix. We reca…
