Enhancing the Charging Performance of Many-Body Quantum Batteries through Landau-Zener Driving

We explore the charging advantages of a many-body quantum battery driven by a Landau-Zener field.

Here we consider both nearest-neighbor and lon...

Description
Summary:We explore the charging advantages of a many-body quantum battery driven by a Landau-Zener field. Such a system may be modeled as a Heisenberg XY spin chain with \(\textit{N}\) interacting spin-\(\frac{1}{2}\) particles under an external magnetic field. Here we consider both nearest-neighbor and long-range spin interactions. The charging performance of this many-body quantum battery is evaluated by comparing Landau-Zener and periodic driving protocols within these interaction regimes. Our findings show that the Landau-Zener driving can offer superior energy deposition and storage efficiency compared to periodic driving. Notably, the Landau-Zener protocol may deliver optimal performance when combined with long-range interactions. The efficiency of a Landau-Zener quantum battery can be significantly enhanced by optimizing key parameters, such as XY anisotropy, the magnitude of the driving field, and interaction strength.
