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…
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…
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…
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…

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…

Irene Ada Picatoste, Alessandra Colla, Heinz-Peter Breuer
Employing a recently developed approach to dynamically emergent quantum thermodynamics, we revisit the thermodynamic behavior of the quantum Otto cycle with a focus on memory effec…

Alessandra Colla, Niklas Neubrand, Heinz-Peter Breuer
We investigate the dynamics of open quantum systems which are initially correlated with their environment. The strategy of our approach is to analyze how given, fixed initial corre…

Alessandra Colla, Heinz-Peter Breuer
We perform a study on quantum entropy production, different kinds of correlations, and their interplay in the driven Caldeira-Leggett model of quantum Brownian motion. The model, t…
