Query: The role of quantum coherence in non-equilibrium entropy production   Thermodynamic irreversibility is well characterized by the entropy production
arising from non-equilibrium quantum processes. We show that the entropy
production of a quantum system undergoing open-system dynamics can be formally
split into a term that only depends on population unbalances, and one that is
underpinned by quantum coherences. The population unbalances are found to
contribute to both an entropy flux and an entropy production rate. The
decoherence, on the other hand, contributes only to the entropy production
rate. This allows us to identify a genuine quantum contribution to the entropy
production in non-equilibrium quantum processes. We make use of such a division
to address the open-system dynamics of a spin $J$ particle, which we describe
in phase space through a spin-coherent representation.
