Hidden Conformal Symmetry of Extremal Kerr-Bolt Spacetimes
Hidden Conformal Symmetry Extremal Kerr-Bolt Spacetimes
2010/12/23
We show that extremal Kerr-Bolt spacetimes have a hidden conformal symmetry. In this regard, we consider the wave equation of a massless scalar field propagating in extremal Kerr-Bolt spacetimes and ...
Late-time Kerr tails: generic and non-generic initial data sets,
generic non-generic superposition
2010/3/17
Three interrelated questions concerning Kerr spacetime late-time tails are considered, specifically the evolutions of generic and non-generic initial data sets, the excitation of "up" modes, and the r...
Kerr-Newman度规中带电Bose子束缚态
带电Bose子束缚态 Kerr-Newman度
2009/8/14
本文指出, 无质量Bose子和Kerr-Newman黑洞不形成束缚态. 有质量的Bose子, 在0<α<√M2－Q2的情况下, 若E≠am+eQr+/2Mr+－Q2则无束缚态; 若E=am+eQr+/2Mr+－Q2则非束缚态存在的必要条件是(22)和(24)式. 在a=√M2－Q2的情况, 束缚态的能量E=√M2－Q2+eQM/2M2－Q2, 当Q=0或者e=0时, 本文结论与de Felic[1...

Bose子束缚态 Kerr-Newman裸奇点
2009/8/14
本文采用线性微分算子的自共轭扩展谱分析法, 讨论了Kerr-Newman型裸奇点与Bose子束缚态问题. 结果表明: 在能隙(—μ,μ)中, Bose子的哈密顿算子只能出现离散谱, 由此推知, 当μ=0时, 不存在Bose子束缚态, 当μ≠0时, Kerr-Newman裸奇点周围有Bose子束缚态形成.
