摘要: 讨论了在无质量BTZ 黑洞背景中的标量场扰动,发现在此情况下,只存在正则模.这一结果 与原始无旋转BTZ 黑洞的情况不同. 这反映了无质量BTZ 黑洞可能是一种与原始无旋转BTZ 黑洞不同的相. Abstract: In this paper, the scalar field perturbations in the background of the massless BTZ black holes was discussed. We found that the massless BTZ hole contains only normal modes in the perturbations. This is different from the perturbation results in the generic nonrotating BTZ black hole background. This special property reflects that the massless BTZ black hole is a different phase from that of the generic nonrotating BTZ hole.
