稳态Kerr-Newman-Kasuya黑洞的视界表面引力

用视界表面引力的定义,即相对于视界静止质点的固有加速度和红移因子的乘积在质点趋于视界时的极限、K le in-Gordon方程与Ham ilton-Jacob i方程3种方法研究了稳态Kerr-Newm an-Kasuya黑洞视界表面引力.其结果表明黑洞的视界表面引力与黑洞所带电荷、磁荷和角动量等因素有关.

Accelerating Effect in Kerr-Newman-Kasuya Field

We have obtained expressions of the accelerating effect in Kerr-Newman Kasuya field. These expressionsinclude four parameters: mass m, angular momentum a, electric charge q, and magnetic charge φ. Furthermore we studyits special case (vi = 0). We get the following conclusion. In the gravitation field of souse mass with electric charge qand magnetic charge b, the acceleration of test particle has not only radial component but also transverse component.When θ = 0, the acceleration is minimum, and when θ = π/2, the acceleration is maximum. Furthermore, we discussthe effects of electric charge q and magnetic charge φ respectively.

Kerr-Newman-Kasuya双荷黑洞隧穿辐射的改进新研究

本文首先通过坐标变换得到了新的Kerr-Newman-Kasuya双荷黑洞解形式。然后运用Euler-Lagrange变分原理,在一般坐标系下对Kerr-Newman-Kasuya双荷黑洞的类时和类光测地线方程作了新的统一推导,并利用Parikh-Wilczek建议的半经典隧穿方法,对有质量带电粒子在Kerr-Newman-Kasuya双荷黑洞视界附近的隧穿辐射作了新的研究,通过计算得到其隧穿几率。研究表明Kerr-Newman-Kasuya双荷黑洞这一类转动黑洞的隧穿辐射可以在一般坐标系下进行分析。
