Daemonic ergotropy: enhanced work extraction from quantum correlations

Quantum thermodynamics: Quantum correlations are key for work extraction! A strong connection exists between the ability of a quantum system to perform thermodynamic work and the amount of quantum correlations that are set in its physical configuration. Here, in this manuscript, the authors have con...
