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…

Dynamics of Heisenberg XYZ spin Quantum Battery
Disha Verma, Indrajith VS, R. Sankaranarayanan
Spin systems have been extensively studied to understand the mechanisms of quantum batteries, which have shown the ability to charge faster than classical counterparts, even in clo…
