Application of the Generalized Work Relation for an N-level Quantum System

Application of the Generalized Work Relation for an N-level Quantum System

An efficient periodic operation to obtain the maximum work from a nonequilibrium initial state in an N–level quantum system is shown. Each cycle consists of a stabilization process followed by an isentropic restoration process. The instantaneous time limit can be taken in the stabilization process f...
