关于非BPS黑洞的精确解和吸引子机制的注记

A Note on Exact Solutions and Attractor Mechanism for Non-BPS Black Holes

Rong-Gen Cai, Da-Wei Pang

摘要:

得到了四维超引力场的两个极值球对称非BPS黑洞解,其中一个带D2-D 6荷,另一个带D 0-D2-D4荷.对于D2-D 6情形,我们不是直接求解运动方程,而是假设解的形式,然后发现假设满足运动方程和约束。我们的D2-D 6解决方案显然是0710.4967中提出的解决方案的对偶。通过对0710.4967中的D 0-D4解执行某些$[SL(2,{\bf Z})]^{3}$对偶变换,获得D 0-D2-D4解。

英文摘要:

We obtain two extremal, spherically symmetric, non-BPS black hole solutions to 4D supergravity, one of which carries D2-D6 charges and the other carries D0-D2-D4 charges. For the D2-D6 case, rather than solving the equations of motion directly, we assume the form of the solution and then find that the assumption satisfies the equations of motion and the constraint. Our D2-D6 solution is manifestly dual to the solution presented in 0710.4967. The D0-D2-D4 solution is obtained by performing certain $[SL(2,{\bf Z})]^{3}$ duality transformations on the D0-D4 solution in 0710.4967.
