Researchers from the Department of Physics at the Indian Institute of Technology Madras, J. Ramya Parkavi, R. Muthuganesan, and V. K. Chandrasekar, have published a study in the journal Physical Review E that delves into the dynamics of a quantum battery (QB) modeled using a dipolar spin system. Their work explores how external parameters and quantum resources influence the energy storage and power output of these innovative energy storage devices.
The study focuses on a two-qubit model to examine the performance of the quantum battery in terms of ergotropy, instantaneous power, capacity, and quantum coherence. By solving the system’s time evolution under cyclic unitary processes, the researchers analyzed how temperature, magnetic field, and Dzyaloshinskii-Moriya (DM) interaction affect the charging behavior and quantum resources of the battery.
The findings reveal that quantum coherence and DM interaction play significant roles in enhancing the energy storage efficiency and power output of the quantum battery. These insights offer promising strategies for designing high-performance quantum energy storage devices. The researchers also investigated the performance of the quantum battery under the influence of a common dephasing environment, which they found limits the long-term work-extraction capability of dipolar quantum batteries.
While quantum batteries are still in the early stages of research, their potential applications in the energy sector could include ultra-fast charging, high-energy density storage, and integration with renewable energy systems. The practical implications of this research could lead to advancements in energy storage technologies, benefiting industries that rely on efficient and reliable energy storage solutions.
The research was published in Physical Review E, a peer-reviewed journal that covers topics in statistical, nonlinear, and soft matter physics. The study contributes to the growing body of knowledge on quantum energy storage and highlights the importance of understanding quantum resources in the development of next-generation energy technologies.
