Floquet time-convolutionless master equation for non-Markovian driven quantum systems
Pietro Follia, Heinz-Peter Breuer, Bassano Vacchini
We study the dynamics of open quantum systems driven by an external time-periodic force. Combining Floquet theory and the time-convolutionless projection operator technique we deri…
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…
Expansion of time-convolutionless non-Markovian quantum master equations: A case study using the Fano-Anderson model
Tim Alhäuser, Heinz-Peter Breuer
We explore the performance of the time-convolutionless (TCL) projection operator technique using the Fano-Anderson model as a test case. Comparing the exact TCL master equation wit…
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 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…
Phase space measures of information flow in open systems: A quantum and classical perspective of non-Markovianity
Moritz F. Richter, Heinz-Peter Breuer
The exchange of information between an open quantum system and its environment, especially the backflow of information from the environment to the open system associated with quant…
Observing Time-Dependent Energy Level Renormalisation in an Ultrastrongly Coupled Open System
Alessandra Colla, Florian Hasse, Deviprasath Palani +3
Understanding how strong coupling and memory effects influence the energy levels of open quantum systems is a complex and challenging problem. Here, we show these effects by probin…
Thermodynamic Roles of Quantum Environments: From Heat Baths to Work Reservoirs
Alessandra Colla, Heinz-Peter Breuer
Environments in quantum thermodynamics usually take the role of heat baths. These baths are Markovian, weakly coupled to the system, and initialized in a thermal state. Whenever on…
Quantum thermodynamics of the spin-boson model using the principle of minimal dissipation
Salvatore Gatto, Alessandra Colla, Heinz-Peter Breuer +1
A recently developed approach to the thermodynamics of open quantum systems, on the basis of the principle of minimal dissipation, is applied to the spin-boson model. Employing a n…
