Local energy assignment for two interacting quantum thermal reservoirs
Alessandra Colla, Bassano Vacchini, Andrea Smirne
Understanding how to assign internal energy, heat, and work in quantum systems beyond weak coupling remains a central problem in quantum thermodynamics, particularly as the differe…
Local and global approaches to the thermodynamics of pure decoherence processes in open quantum systems
Irene Ada Picatoste, Alessandra Colla, Heinz-Peter Breuer
We study the nonequilibrium thermodynamics of pure decoherence processes in open quantum systems coupled to a thermal reservoir. We review various definitions of central quantities…
Unveiling coherent dynamics in non-Markovian open quantum systems: exact expression and recursive perturbation expansion
Alessandra Colla, Heinz-Peter Breuer, Giulio Gasbarri
We introduce a systematic framework to derive the effective Hamiltonian governing the coherent dynamics of non-Markovian open quantum systems. By applying the minimal dissipation p…
Recursive perturbation approach to time-convolutionless master equations: Explicit construction of generalized Lindblad generators for arbitrary open systems
Alessandra Colla, Heinz-Peter Breuer, Giulio Gasbarri
We develop a recursive perturbative expansion for the time-convolutionless (TCL) generator of an open quantum system in a generalized Lindblad form. This formulation provides a sys…
