Quantum Otto engines at relativistic energies
Nathan M. Myers, Obinna Abah, Sebastian Deffner
Relativistic quantum systems exhibit unique features not present at lower energies, such as the existence of both particles and antiparticles, and restrictions placed on the system…
Energy optimization of two-level quantum Otto machines
Satnam Singh, Obinna Abah
We present the spin quantum Otto machine under different optimization criterion when function either as a heat engine or a refrigerator. We examine the optimal performance of the h…
A single-atom heat engine
Johannes Roßnagel, Samuel Thomas Dawkins, Karl Nicolas Tolazzi +4
We report the experimental realization of a single-atom heat engine. An ion is confined in a linear Paul trap with tapered geometry and driven thermally by coupling it alternately…
Quantum work statistics of linear and nonlinear parametric oscillators
Sebastian Deffner, Obinna Abah, Eric Lutz
We consider the nonequilibrium work distribution of a quantum oscillator with modulated angular frequency. We examine the discrete-to-continuous transition of the distribution as t…
