A research team at the University of Genova has developed the spin quantum battery, an energy storage system that uses the spin degrees of freedom of particles.
The team tested the new spin quantum battery design and charging protocol in a series of initial experiments.
Quantum many-body theory and non-equilibrium physics are longstanding research areas within the quantum condensed matter theory group led by Maura Sassetti at the University of Genova, according to senior author Dario Ferraro.that his work focuses on quantum batteries—miniaturized devices designed to store energy using quantum mechanical principles. He saw an opportunity to advance this research through Riccardo Grazi’s master’s thesis.
The developed protocol offers several advantages over existing spin quantum battery designs, particularly by enabling the battery to charge without relying on an external field. Furthermore, the main results of their work include the development of an alternative charging protocol for spin quantum batteries, which relies on time-dependent modulation of one of the system’s internal parameters, as well as the ability to study this protocol in a system with a very large number of elements.
