论文摘要
在本文中,通过标量颗粒和费米子的吸收来研究五维球体对称拓扑黑洞的扩展相位空间中的过度充电问题和热力学。宇宙常数被认为是与压力相关的变量,其共轭数量是热力学体积。热力学的第一定律被回收。第二定律在极端和近超级黑洞的扩展相空间中违反。通过事件视野的存在来测试过多的收费问题。事件范围由公制组件$ f(r)$确定。最后阶段的度量分量的最小值表明,极端和近超级黑洞的收费不能过多。
In this paper, the overcharging problem and thermodynamics in the extended phase spaces of the five-dimensional spherically symmetric topological black holes are investigated by absorptions of scalar particles and fermions. The cosmological constant is regarded as a variable related to pressure and its conjugate quantity is a thermodynamic volume. The first law of thermodynamics is recovered. The second law is violated in the extended phase space of the extremal and near-extremal black holes. The overcharging problem is tested by the existence of the event horizons. The event horizon is determined by the metric component $f(r)$. The minimal values of the metric component at the final stage show that the extremal and near-extremal black holes can not be overcharged.
