高维时空中的环面螺旋弦

Toroidal Spiral Strings in Higher-dimensional Spacetime

Takahisa Igata, Hideki Ishihara

摘要:

本文报道了我们在五维Kerr-AdS黑洞中对环形螺旋对称测试弦Nambu-Goto方程可分性的研究进展。特别地,对于一类特殊的环形螺旋线,我们证明了在Kerr背景和等角动量的Kerr-AdS背景两种情况下变量的完全分离。我们还得到了黑洞周围的霍普夫环和一般的环形螺旋在闵可夫斯基背景下的动力学解。

英文摘要:

We report on our progress in research of separability of the Nambu-Goto equation for test strings with a symmetric configuration in a shape of toroidal spiral in a five-dimensional Kerr-AdS black hole. In particular, for a Hopf loop string which is a special class of the toroidal spirals, we show the complete separation of variables occurs in two cases, Kerr background and Kerr-AdS background with equal angular momenta. We also obtain the dynamical solution for the Hopf loop around a black hole and for the general toroidal spiral in Minkowski background.
