在计算Kerr/CFT对应之后，我们将Brown-Henneaux方法应用于5D极值旋转的Kaluza-Klein黑洞，这不是基于超对称性或弦理论。我们发现，在适当的边界条件下，可以得到两个完全不同的Virasoro代数作为渐近对称代数。用Cardy公式计算了两种边界条件下的微观熵，它们与Bekenstein-Hawking熵完全一致。旋转的Kaluza-Klein黑洞包含一个四维双子Reissner-Nordstrom黑洞和Myers-Perry黑洞。由于与这些黑洞相对应的D膜组态是已知的，我们的分析将有助于更深入地理解手征CFT2‘S对偶到极值黑洞。
We apply Brown-Henneaux's method to the 5D extremal rotating Kaluza-Klein black holes essentially following the calculation of the Kerr/CFT correspondence, which is not based on supersymmetry nor string theory. We find that there are two completely different Virasoro algebras that can be obtained as the asymptotic symmetry algebras according to appropriate boundary conditions. The microscopic entropies are calculated by using the Cardy formula for both boundary conditions and they perfectly agree with the Bekenstein-Hawking entropy. The rotating Kaluza-Klein black holes contain a 4D dyonic Reissner-Nordstrom black hole and Myers-Perry black hole. Since the D-brane configurations corresponding to these black holes are known, we expect that our analysis will shed some light on deeper understanding of chiral CFT2's dual to extremal black holes.
