The irreversible production of the waste energy due to the quantum friction is quantitatively analyzed in a forward-backward unitary transform of the system Hamiltonian by using the quantum relative entropy between the actual density matrix obtained in a parametric transformation and the one in a reversible adiabatic process. Analyzing the role of total transformation time and the different pulse control schemes on the internal friction reveal the non-monotone character of the internal friction as a function of the total protocol time and the possibility for almost frictionless solutions in finite-time transformations.eninfo:eu-repo/semantics/closedAccessInternal FrictionQuantum ThermodynamicsQuantum Adiabatic ProcessQuantum Relative EntropyArticle10.1088/0031-8949/91/7/0751019172-s2.0-84978239467Q2WOS:000378864400018Q3
