Cluster Ising quantum batteries can mimic super-extensive charging power
Anna Pavone, Federico Luigi Cavagnaro, Matteo Carrega +3
Quantum batteries, miniaturized devices able to store and release energy on demand, are promising both because their intrinsic energy and time scales can match those of other quant…
Charging Quantum Batteries via Dissipative Quenches
Riccardo Grazi, Donato Farina, Niccolò Traverso Ziani +1
We investigate work extraction in open quantum batteries composed of interacting spin chains weakly coupled to engineered environments. Focusing on two- and four-qubit XX models in…
Finite-Time Protocols Stabilize Charging in Noisy Ising Quantum Batteries
Riccardo Grazi, Henrik Johannesson, Dario Ferraro +1
Reliable charging protocols are crucial for advancing quantum batteries toward practical use. We investigate a transverse-field Ising chain as a quantum battery, focusing on the co…
Universal features of non-analytical energy storage in quantum critical quantum batteries
Riccardo Grazi, Dario Ferraro, Niccolò Traverso Ziani
Quantum batteries are quantum mechanical systems able to store and release energy in a controlled fashion. Among them, a special role is played by quantum structures defined as net…
Charging free fermion quantum batteries
Riccardo Grazi, Fabio Cavaliere, Maura Sassetti +2
The performances of many-body quantum batteries strongly depend on the Hamiltonian of the battery, the initial state, and the charging protocol. In this article we derive an analyt…
Charging a Dimerized Quantum XY Chain
Riccardo Grazi, Fabio Cavaliere, Niccolò Traverso Ziani +1
Quantum batteries are quantum systems designed to store energy and release it on demand. The optimization of their performance is an intensively studied topic within the realm of q…
