该论文通过Carroll展开得到chiral Carroll弦在弯曲时空中的作用量，并研究其接近史瓦西黑洞时的动力学，发现弦在视界上有左右涨落并在Rindler时空中呈现非平凡运动。
AI 中文摘要
我们通过对相对论性闭玻色弦的作用量进行光速$c$的Carroll展开，得到了在弯曲的弦-Carroll目标时空中运动的chiral Carroll弦的作用量。将此框架应用于接近$4$维史瓦西黑洞的经典闭玻色弦，我们研究了当弦表现为chiral Carroll弦且以近视界弦-Carroll展开几何作为目标时空时的动力学。我们发现，chiral Carroll弦在视界上可以有左移或右移的涨落，同时在Rindler时空中表现出依赖于这些视界涨落的非平凡运动。
英文摘要
We obtain the action for the chiral Carroll string moving in a curved string-Carroll target spacetime from a Carroll expansion, in powers of the speed of light $c$, of the action for the relativistic closed bosonic string. Applying this setup to a classical closed bosonic string approaching the $4$-dimensional Schwarzschild black hole, we study the dynamics of the string when it behaves as a chiral Carroll string with the near-horizon string-Carroll expanded geometry as the target spacetime. We find that the chiral Carroll string can have either left-moving or right-moving fluctuations on the horizon, while exhibiting a non-trivial motion in the Rindler spacetime which depends on these horizon fluctuations.
