Contributions to single-shot energy exchanges in open quantum systems

Abstract: The exchange of energy between a classical open system and its environment can be analysed for a single run of an experiment using the phase space trajectory of the system. By contrast, in the quantum regime such energy exchange processes must be defined for an ensemble of runs of the same experiment based on the reduced system density matrix. Single-shot approaches have been proposed for quantum systems that are weakly coupled to a heat bath. However, a single-shot analysis for a quantum system that is entang… Show more

“…By introducing a time-dependent component in this magnetic field, along with the variation of the gate voltage would lead to a scenario like the one studied in the present work. At finite T , the effects we have studied could be relevant in the implementation of driving protocols for thermal machines, [50][51][52][53][54][55][56] as well as in the discussion of shortcuts to adiabaticity. [57][58][59]…”

“…Within the framework of thermodynamics, it is possible to study different correlations such as system-environment correlation, correlation between different constituents of the system itself, or even correlations within the environment. It is known that system-environment correlation is an important element in the system's dynamical equation and accordingly in the thermodynamic properties of the system, e.g., in energy transfer [1][2][3][4]. In particular, in the strong coupling regime correlation comes into play indirectly through interactions [5,6].…”

“…With recent developments in the rapidly growing field of quantum information science, numerous novel concepts have been introduced and used for a plethora of systems and applications in physics, communications, and computation [1,2], where correlations (quantum in particular) play a key role. For example, in quantum thermodynamics [3], it is known that correlations can be a resource in energy transfer [4,5], heat and work conversion [6][7][8][9][10], entropy exchange [11][12][13], and in the performance of quantum heat engines [14]. Correlations can also have implications on the size of the gap in the energy spectrum of correlated systems [15].…”
