Magnetic Dipolar Quantum Battery with Spin-Orbit Coupling

A magnetic dipolar system is investigated, influenced by the -component of Zeeman splitting, Dzyaloshinsky-Moriya (DM) interaction, and Kaplan-Shekhtman-Entin-Wohlman-Aharony (KSEA) exchange interaction, with emphasis on the role of quantum resources in both closed and open settings. By analyzing the Gibbs thermal state and solving the Lindblad master equation, the behavior of quantum coherence, discord, and entanglement is studied under thermal equilibrium and dephasing noise. After exploring these resources, the model is applied to a closed quantum battery (QB). These results show that while Zeeman splitting degrades quantum resources in noisy and thermal regimes, it enhances QB performance by improving ergotropy, anti-ergotropy, storage capacity, and coherence during cyclic charging. The axial parameter further amplifies performance, leading to coherence saturation and persistent ergotropy growth, in line with the notion of incoherent ergotropy. KSEA interaction and the rhombic term consistently preserve coherence and entanglement under noise, thereby strengthening QB functionality. DM interaction mitigates thermal degradation of resources in the Gibbs state and improves performance, though its effect is limited under Pauli- dephasing. Diverse behaviors are revealed, including increased ergotropy without coherence and the coexistence of coherence with zero extractable work. Finally, the nuclear magnetic resonance (NMR) is proposed as a feasible platform for experimental implementation.
