Symmetry-induced fluctuation relations in open quantum systems

چکیده

We derive a general scheme to obtain quantum fluctuation relations for dynamical observables in open systems. For concreteness, we consider Markovian nonunitary dynamics that is unraveled terms of jump trajectories and exploit techniques from the theory large deviations like tilted ensemble Doob transform. Our results here generalize system previously obtained classical systems add vast literature on domain, but without resorting standard two-point measurement scheme. illustrate our findings with three examples highlight discuss main features result.

Fluctuation theorems in driven open quantum systems

The characteristic function for the joint measurement of the changes of two commuting observables upon an external forcing of a quantum system is derived. In particular, the statistics of the internal energy, the exchanged heat and the work of a quantum system that weakly couples to its environment is determined in terms of the energy changes of the system and the environment due to the action ...

Fluctuation theorem for arbitrary open quantum systems.

Based on the observation that the thermodynamic equilibrium free energy of an open quantum system in contact with a thermal environment is the difference between the free energy of the total system and that of the bare environment, the validity of the Crooks theorem and of the Jarzynski equality is extended to open quantum systems. No restrictions on the nature of the environment or on the stre...

Colloquium: Quantum fluctuation relations: Foundations and applications

Two fundamental ingredients play a decisive role in the foundation of fluctuation relations: the principle of microreversibility and the fact that thermal equilibrium is described by the Gibbs canonical ensemble. Building on these two pillars the reader is guided through a self-contained exposition of the theory and applications of quantum fluctuation relations. These are exact results that con...

Isometric fluctuation relations for equilibrium states with broken symmetry.

We derive a set of isometric fluctuation relations, which constrain the order parameter fluctuations in finite-size systems at equilibrium and in the presence of a broken symmetry. These relations are exact and should apply generally to many condensed-matter physics systems. Here, we establish these relations for magnetic systems and nematic liquid crystals in a symmetry-breaking external field...
