Interaction-Enhanced Ergotropy in Phase-Driven Andreev Bound State Quantum Batteries
Disha Verma, B. Vigneshwar, R. Sankaranarayanan
We investigate a phase-driven quantum battery composed of two interacting Andreev bound state (ABS) units, providing a minimal superconducting platform for coherent energy storage.…

Ergotropy Dynamics in a Dissipative Graphene Quantum Battery
Disha Verma, Indrajith VS, R. Sankaranarayanan
We investigate ergotropy dynamics in a graphene-based quantum battery modeled as a four-level spin--valley system under different dissipative environments. The battery is charged v…

Ergotropy and Work Extraction in Quantum Heat Engines via Quantum Channels
Indrajith VS, Disha Verma
This paper explores quantum heat engines based on qubit and qutrit working media interacting with thermal environments through generalized amplitude damping (GAD) channels. We inve…
