Ergotropy of multipartite entangled states in the quantum atmosphere
Ruopu Sun, Xiaofen Huang
We investigate the ergotropy of tripartite Greenberger-Horne-Zeilinger (GHZ) and W states in the quantum atmosphere of a Schwarzschild black hole, focusing on how the extractable w…

Evolution of quantum imaginarity in black hole quantum atmosphere
Ruopu Sun, Xiaofen Huang
Quantum imaginarity, as a critical resource metric for quantifying intrinsic nonreal coherence encoded in quantum states, exhibits nontrivial evolutionary behaviors in curved space…
