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…
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…
