Charging a quantum battery from the Bloch sphere
C. A. Downing, M. S. Ukhtary
We reconsider the quantum energetics and quantum thermodynamics of the charging process of a simple, two-component quantum battery model made up of a charger qubit and a single--ce…

Switching rates in Kerr resonator with two-photon dissipation and driving
V. Yu. Mylnikov, S. O. Potashin, M. S. Ukhtary +1
We analytically investigate the switching rate in a two-photon driven Kerr oscillator with finite detuning and two-photon dissipation. This system exhibits quantum bistability and…

Energy storage in a continuous-variable quantum battery with nonlinear coupling
C. A. Downing, M. S. Ukhtary
In the quantum world, the process of energy storage can be enhanced thanks to various nonclassical phenomena. This inspiring fact suggests quantum batteries as plausible sources of…
