AI 中文总结

研究史瓦西黑洞量子大气中霍金辐射影响下二分Werner态的几何量子失协,发现其在不同区域的非单调行为及极值位置,还明确了哈特尔霍金常数和事件视界半径对量子关联重新分布强度的相反影响。

AI 中文摘要

我们研究了史瓦西黑洞量子大气中受霍金辐射影响的二分Werner态的几何量子失协。发现在物理可及区域,几何量子失协呈现非单调行为:随归一化径向距离增加先减小后增大,而在物理不可及区域则相反。几何量子失协的显著极值恰好出现在对应霍金辐射峰值强度的位置。此外,发现哈特尔霍金常数和事件视界半径对量子关联重新分布强度有相反影响:哈特尔霍金常数越大增强重新分布效应,事件视界半径越大则抑制它。

英文摘要

We investigate the geometric quantum discord of bipartite Werner states influenced by Hawking radiation in the quantum atmosphere of a Schwarzschild black hole. We find that the geometric quantum discord in the physically accessible region exhibits a nonmonotonic behavior: it first decreases and then increases as the normalized radial distance increases, while the discord in the physically inaccessible region shows the exact opposite trend. A pronounced extremum of geometric quantum discord occurs precisely at the position corresponding to the peak intensity of Hawking radiation. Furthermore, we find that the Hartle Hawking constant and the event horizon radius exert opposite effects on the strength of quantum correlation redistribution: a larger Hartle Hawking constant enhances the redistribution effect, whereas a larger event horizon radius suppresses it.
