Claims

C1strongest claim

By adjusting experimentally accessible parameters, such as reservoir occupation and coherent coupling strength, the non-Hermitian Liouvillian spectrum can approach an exceptional point. This increases the spectral gap and accelerates the approach to steady state. As a result, this mechanism significantly enhances asymptotic charging power without relying on many-body collectivity or steady coherence.

C2weakest assumption

That the long-term dynamics remain confined to a low-dimensional manifold of slow Liouvillian modes and that tuning reservoir occupation and coupling strength to the exceptional point does not introduce additional decoherence channels or invalidate the Markovian description.

C3one line summary

Tuning parameters in a three-level open quantum battery near a Liouvillian exceptional point widens the spectral gap and speeds charging to the steady state without needing collective effects or persistent coherence.
