在quintessenc中极端整体单极子黑洞的拟正则模

Quasinormal modes of the near extremal black hole with quintessence-like matter and a deficit solid angle

利用WKB法,研究了在quintessenc中极端整体单极子黑洞的拟正则模,主要目的在于研究拟正则频率和黑洞的特征参量之间的关系.研究结果表明;拟正则频率的实部和虚部均随着角量子数的增加而增加;拟正则频率实部和虚部的绝对值随着立体亏损角参量的增加而增加,而与在r=1处的quintessence的密度大小以及黑洞质量的关系正好相反.

Using WKB method, quasinormal modes of the near extremal global monopole black hole with quintessence matter are studied. We investigate the relations between quasinormal frequencies and the characteristic parameters of this black hole. The results show that both the real part and the imaginary part of quasinormal frequencies increase with muhipole index, the real part and the absolute value of the imaginary part increase as the deficit solid angle increasing, and we also discuss the relations of qusinormal modes with respect to the density of quintessence at r = 1 and the mass of black hole, respectively.
