论文摘要
我们研究了黑洞周围的Tachyon场的存在的影响。我们表明,与普通的规范标量场不同,在存在tachyon场的情况下,黑洞质量的时间演变取决于该场的潜力。通过考虑几种类型的潜力,我们研究了黑洞质量及其时间演变的行为,并找到了一些有趣的结果。我们发现,速元场的存在导致质量积聚到黑洞中。我们还表明,使用线性和山顶电势,在参数空间的某些范围内,即使没有任何鹰辐射,黑洞的质量也可以减少。
We study the effects of the presence of the tachyon field around the black hole. We show that in presence of the tachyon field, unlike the ordinary canonical scalar field, the time evolution of the black hole mass depends on the potential of this field. By considering several types of potential, we study the behavior of the black hole mass and its time evolution and find some interesting results. We find that the presence of the tachyon field causes the accretion of the mass into the black hole. We also show that with linear and hilltop potentials, in some ranges of the parameters space, the mass of the black hole can decrease even without any Hawking radiation.
