Non-linear regime for enhanced performance of an Aharonov-Bohm heat engine
Géraldine Haack, Francesco Giazotto
Thermal transport and quantum thermodynamics at the nanoscale is nowadays garnering an increasing attention, in particular in the context of quantum technologies. Experiments relev…
Operational nonclassicality in minimal autonomous thermal machines
Jonatan Bohr Brask, Fabien Clivaz, Géraldine Haack +1
Thermal machines exploit interactions with multiple heat baths to perform useful tasks, such as work production and refrigeration. In the quantum regime, tasks with no classical co…
Quantum speed-up in collisional battery charging
Stella Seah, Martí Perarnau-Llobet, Géraldine Haack +2
We present a collision model for the charging of a quantum battery by identical nonequilibrium qubit units. When the units are prepared in a mixture of energy eigenstates, the ener…
Photonic heat rectification in a coupled qubits system
Andrea Iorio, Elia Strambini, Géraldine Haack +2
We theoretically investigate a quantum heat diode based on two interacting flux qubits coupled to two heat baths. Rectification of heat currents is achieved by asymmetrically coupl…
Signatures of Liouvillian exceptional points in a quantum thermal machine
Shishir Khandelwal, Nicolas Brunner, Géraldine Haack
Viewing a quantum thermal machine as a non-Hermitian quantum system, we characterize in full generality its analytical time-dependent dynamics by deriving the spectrum of its non-H…
