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…

Nonlocal contributions to ergotropy: A thermodynamic perspective
B. Vigneshwar, R. Sankaranarayanan
Nonlocality is a defining feature of quantum mechanics and has long served as a key indicator of quantum resources since the formulation of Bell's inequalities. Identifying the con…
