论文摘要
我们构建了新型的黑色弦，它们既不是时间翻译不变的，也不是轴对称，也不是弦乐方向的翻译不变的，但是仍然有螺旋的杀伤矢量场。这些解决方案是从$ d = 6 $ Myers-Perry黑弦的超级不稳定性分支的，具有相等的角动量。我们将这些解决方案归因于{\ it黑色谐振弦}，我们发现它们的熵比Myers-Perry黑色琴弦的能量和Angular Momenta都具有更多的熵。我们还构建了Kaluza-klein Geons，该Geons共享黑色谐振弦的对称性，但却是无线的。与其他超级系统不同，Kaluza-Klein Geons并不是黑色谐振弦的无线限制，而是完全独立的解决方案。
We construct novel black strings that are neither time-translation invariant, nor axisymmetric, nor translationally invariant in the string direction, but nevertheless have a helical Killing vector field. These solutions branch from the superradiant instability of $D=6$ Myers-Perry black strings with equal angular momenta. We coin these solutions as {\it black resonator strings} and we find that they have more entropy than Myers-Perry black strings for the energies and angular momenta where both solutions coexist. We also construct Kaluza-Klein geons, which share the symmetries of black resonator strings, but are horizonless. Unlike in other superradiant systems, Kaluza-Klein geons are not the horizonless limit of black resonator strings and are instead entirely separate solutions.
