Dissipative dynamics activate finite ergotropy from thermal quantum spin chains, with collective effects creating temperature- and size-dependent steady-state passivity via dark subspaces, while dephasing suppresses extraction.
A hybrid open quantum battery uses an auxiliary coherent qubit to generate a decoherence-free subspace that stabilizes steady-state ergotropy under dissipation and finite temperature.
Coupling a qubit quantum battery to a harmonic-oscillator catalyst produces transient negative energy flux that correlates with increased extractable work (ergotropy) under dephasing and dissipation.
