Microcanonical and resource-theoretic derivations of the thermal state of a quantum system with noncommuting charges

A central concept in thermodynamics is the thermal state, which is the one towards which the system relaxes. Here, the authors derive the same state, through three different approaches, in the case of a quantum system whose conserved quantities correspond to operators that do not commute with one an...

Sumario:A central concept in thermodynamics is the thermal state, which is the one towards which the system relaxes. Here, the authors derive the same state, through three different approaches, in the case of a quantum system whose conserved quantities correspond to operators that do not commute with one another.
