具有奇异标量物质的黑洞内部物理

Physics of the interior of a black hole with an exotic scalar matter

Andrey Doroshkevich, Jakob Hansen, Dmitriy Novikov, Igor Novikov, Dong-Ho Park, Alexander Shatskiy

摘要:

我们使用一个数值代码来考虑Reissner-Nordstrom黑洞被一个奇异的标量场(建模为一个自由的无质量的标量场,其能量动量张量的符号相反)照射时所产生的非线性过程。这些过程与普通标量场脉冲辐照同一个黑洞时所产生的过程完全不同。在我们的例子中,我们没有观察到在时空的T区域中产生一个类空的强奇点。研究了具有负能量密度的奇异标量场在引力场中的反聚焦效应和质量函数的演化。我们证明了当黑洞受到奇异标量场的强脉冲照射时,黑洞消失的过程。

英文摘要:

We use a numerical code to consider the nonlinear processes arising when a Reissner-Nordstrom black hole is irradiated by an exotic scalar field (modelled as a free massless scalar field with an opposite sign for its energy-momentum tensor). These processes are quite different from the processes arising in the case of the same black hole being irradiated by a pulse of a normal scalar field. In our case, we did not observe the creation of a spacelike strong singularity in the T-region of the space-time. We investigate the antifocusing effects in the gravity field of the exotic scalar field with the negative energy density and the evolution of the mass function. We demonstrate the process of vanishing of the black hole when it is irradiated by a strong pulse of an exotic scalar field.
