Anomalous discharging of quantum batteries: the ergotropic Mpemba effect
Ivan Medina, Oisín Culhane, Felix C. Binder +2
Anomalous thermal relaxation is ubiquitous in nonequilibrium statistical mechanics. An emblematic example of this is the Mpemba effect, where an initially ``hot'' system cools fast…

Thermodynamics of the quantum Mpemba effect
Mattia Moroder, Oisín Culhane, Krissia Zawadzki +1
We investigate the quantum Mpemba effect from the perspective of non-equilibrium quantum thermodynamics by studying relaxation dynamics of quantum systems coupled to a Markovian he…

Powering an autonomous clock with quantum electromechanics
Oisin Culhane, Michael J. Kewming, Alessandro Silva +2
We theoretically analyse an autonomous clock comprising a nanoelectromechanical system, which undergoes self-oscillations driven by electron tunnelling. The periodic mechanical mot…
