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…

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…

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…

On positively divisible non-Markovian processes

Bilal Canturk, Heinz-Peter Breuer

There are some positively divisible non-Markovian processes whose transition matrices satisfy the Chapman-Kolmogorov equation. These processes should also satisfy the Kolmogorov co…
