AI 中文摘要
我们计算了Reissner-Nordstrom黑洞上有质量带电量子标量场的标量凝聚、电荷流和应力-能量张量的重整化期望值，该标量场质量足够大，不存在经典超辐射。我们给出了Boulware、Unruh和Hartle-Hawking态的结果：Hartle-Hawking态的重整化期望值采用高效且准确的模式求和方案计算，另外两个态则采用态减法。数值方法的高效性使我们能探索大部分参数空间，包括近极端黑洞电荷和接近超辐射极限的标量场质量。
英文摘要
We compute the renormalized expectation values of the scalar condensate, charge current and stress-energy tensor for a massive charged quantum scalar field on a Reissner-Nordstrom black hole. The mass of the scalar field is sufficiently large that classical superradiance is absent. We present results for the Boulware, Unruh and Hartle-Hawking states. Renormalized expectation values in the Hartle-Hawking state are computed using an efficient and accurate mode sum prescription, and for the other two states we employ state subtraction. The efficiency of our numerical method enables us to explore a large part of the parameter space, including near-extremal black hole charges and scalar field masses close to the superradiant limit.
