Current fluctuations in open quantum systems: Bridging the gap between quantum continuous measurements and full counting statistics
Gabriel T. Landi, Michael J. Kewming, Mark T. Mitchison +1
Continuously measured quantum systems are characterized by an output current, in the form of a stochastic and correlated time series which conveys crucial information about the und…
Quantum stochastic thermodynamics in the mesoscopic-leads formulation
Laetitia P. Bettmann, Michael J. Kewming, Gabriel T. Landi +2
We introduce a numerical method to sample the distributions of charge, heat, and entropy production in open quantum systems coupled strongly to macroscopic reservoirs, with both te…
Entropy production in the mesoscopic-leads formulation of quantum thermodynamics
Artur M. Lacerda, Michael J. Kewming, Marlon Brenes +4
Understanding the entropy production of systems strongly coupled to thermal baths is a core problem of both quantum thermodynamics and mesoscopic physics. While there exist many te…
Quantum thermodynamics with fast driving and strong coupling via the mesoscopic leads approach
Artur M. Lacerda, Archak Purkayastha, Michael Kewming +2
Understanding the thermodynamics of driven quantum systems strongly coupled to thermal baths is a central focus of quantum thermodynamics and mesoscopic physics. A variety of diffe…
First Passage Times for Continuous Quantum Measurement Currents
Michael J. Kewming, Anthony Kiely, Steve Campbell +1
The First Passage Time (FPT) is the time taken for a stochastic process to reach a desired threshold. In this letter we address the FPT of the stochastic measurement current in the…
Demonstration of energy extraction gain from non-classical correlations
Alexander Stahl, Michael Kewming, John Goold +3
Within the framework of microscopic thermodynamics, correlations can play a crucial role for energy extraction. Our work sheds light on this connection by demonstrating that entang…
