论文摘要
长期以来，人们一直认为，一个高度兴奋的弦可以被视为黑洞：弦和黑洞之间的对应原理，而最近的研究发现黑洞是混乱的特征。这表明高度激发的字符串是黑洞混沌性的来源。我们研究了弦振幅的混乱性，其中tachyon散布着一个高度激发的弦。我们在振幅中提取混乱的策略是对经典散射的瞬态混乱分析的概括。我们在传入/传出散射角的图中寻找分形结构，其中传出角度定义为振幅的最大极点。在我们的策略中，我们无法确定散射数据中的任何分形结构。我们还讨论了提取混乱的其他可能的设置和策略，希望我们目前的工作是迈向弦散射幅度混乱的一步。
It has long been thought that a highly excited string can be regarded as a black hole: the correspondence principle between strings and a black hole, while recent studies found that black holes are characterized by chaos. This suggests that highly excited strings are the source of the black hole chaoticity. We study the chaoticity of a string amplitude where a tachyon is scattered by a highly excited string. Our strategy to extract the chaos in the amplitude is a generalization of the transient chaos analysis for classical scattering. We look for the fractal structure in the plots of incoming/outgoing scattering angles, where the outgoing angle is defined as the maximum pole of the amplitude. Within our strategy, we could not identify any fractal structure in the scattering data. We also discuss other possible setups and strategies to extract the chaos, hoping that our present work serves as a step toward the formulation of chaos in string scattering amplitudes.
