具有导数耦合的静态球对称黑洞的量子正规模

Quansinormal modes of static and spherically symmetric black holes with the derivative coupling

Shuang Yu, Changjun Gao

摘要:

研究了一类静态球对称黑洞在导数耦合下的拟正规模。在黑洞准正规模的研究中,导数耦合很少被关注。具体地,我们研究了导数耦合对四种黑洞的准正规模的影响。它们分别是Reissner-Nordstrom黑洞、Barclay黑洞、受非连通几何启发的黑洞和Barclay on黑洞。这些黑洞不是真空爱因斯坦方程的解,这保证了导数耦合的影响不是微不足道的。我们发现导数耦合对准正规模的影响大致模拟泛音数。换句话说,由于增加耦合常数和泛音数,准正规模频率的趋势存在定性的相似性。

英文摘要:

We investigate the quasinormal modes of a class of static and spherically symmetric black holes with the derivative coupling. The derivative coupling has rarely been paid attention to the study of black hole quasinormal modes. Specifically, we study the effect of derivative coupling on the quasinormal modes for four kinds of black holes. They are Reissner-Nordstrom black holes, Bardeen black holes, noncommunicative geometry inspired black holes and dilaton black holes. These black holes are not the solutions of vacuum Einstein equations which guarantees the effect of derivative coupling is not trivial. We find the influence of derivative coupling on the quasinormal modes roughly mimics the overtone numbers. In other words, there is a qualitative similarity in the trend of quasinormal modes frequencies due to increasing either the coupling constant and the overtone number.
