D=5最大规范超引力中新的旋转非极值黑洞

New Rotating Non-Extremal Black Holes in D=5 Maximal Gauged Supergravity

Jianwei Mei, C. N. Pope

摘要:

在最大五维规范超引力下,我们得到了新的非极值旋转黑洞解。它们的特点是由五个参数,与质量,两个角动量,和两个独立指定的电荷参数。与SO(6)规范群的U(1)^3 Cartan子群相关的三个电荷中有两个是相等的,而第三个可以独立地指定。这些新的解决方案概括了所有以前已知的旋转解决方案,在五维规范超引力与独立的角动量。它们描述了规则的黑洞,只要参数在适当的范围内,从而避免了裸奇点和封闭类时曲线(CTC)。我们还构造了BPS极限,并表明,如果以适当的方式进一步限制参数,则会出现规则的超对称黑洞或拓扑孤子。

英文摘要:

We obtain new non-extremal rotating black hole solutions in maximal five-dimensional gauged supergravity. They are characterised by five parameters, associated with the mass, the two angular momenta, and two independently-specifiable charge parameters. Two of the three charges associated with the U(1)^3 Cartan subgroup of the SO(6) gauge group are equal, whilst the third can be independently specified. These new solutions generalise all the previously-known rotating solutions in five-dimensional gauged supergravity with independent angular momenta. They describe regular black holes, provided the parameters lie in appropriate ranges so that naked singularities and closed-timelike curves (CTCs) are avoided. We also construct the BPS limit, and show that regular supersymmetric black holes or topological solitons arise if the parameters are further restricted in an appropriate manner.
