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…
Quantum Otto cycle in the Anderson impurity model
Salvatore Gatto, Alessandra Colla, Heinz-Peter Breuer +1
We study the thermodynamic performance of a periodic quantum Otto cycle operating on the single-impurity Anderson model. Using a decomposition of the time-evolution generator based…
Fluctuations of path-dependent thermodynamic quantities in open quantum systems via two-point system-only measurements
Alessandra Colla, Andrea Smirne, Heinz-Peter Breuer +1
We propose a method to evaluate general thermodynamic fluctuations in open quantum systems, based on performing a two-point measurement scheme on the system using dynamics-dependen…
Local approach to entropy production in the nonequilibrium dynamics of open quantum systems
Irene Ada Picatoste, Alessandra Colla, Heinz-Peter Breuer
We discuss fundamental features of the local expression for the entropy production rate of the nonequilibrium quantum dynamics of open systems and its relations to memory effects a…
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…
