Born-Infeld型电动力学与磁黑洞

Born--Infeld-type electrodynamics and magnetic black holes

S. I. Kruglov

摘要:

本文研究了一个与广义相对论耦合的具有三个参数的Born-Infeld型非线性电动力学模型。作为一个特殊的情况玻恩-因菲尔德电动力学再现。在该模型中,点状带电粒子中心的电场不存在奇异性,电荷的自能是有限的。对磁化黑洞进行了研究,得到了磁化黑洞的解.我们证明了对于模型的某些参数,黑洞是正则的。我们发现在$r\rightarrow\infty$和$r\rightarrow 0$的度量和质量函数的渐近,和Reissner-Nordström解决方案的修正。研究了黑洞的热力学。我们计算了黑洞的Hawking温度,表明黑洞是不稳定的,在所考虑的模型中存在相变。

英文摘要:

We investigate a Born--Infeld-type model of nonlinear electrodynamics, possessing three parameters, coupled with general relativity. As a particular case Born--Infeld electrodynamics is reproduced. There is no singularity of the electric field at the centre of point-like charged particles and self-energy of charges is finite in this model. The magnetized black hole is studied and solutions are obtained. We demonstrate that for some parameters of the model the black hole is regular. We find the asymptotic of the metric and mass functions at $r\rightarrow\infty$ and $r\rightarrow 0$, and corrections to the Reissner--Nordström solution. Thermodynamics of black holes is investigated. We calculate the Hawking temperature of black holes and show that black holes are not stable and there are phase transitions in the model under consideration.
