论文摘要
我们通过使用Neumann-Rosochatius（NR）模型研究了在IIB字符串型中的两个正交堆栈的1+1维相交的背景下进行刚性旋转和脉动弦。从探测基本弦的Polyakov作用开始，我们表明，在存在通量的情况下，广义的ANSATZ将系统降低到一个维度NR模型中。利用该模型的可集成结构来分析旋转和振荡弦溶液。我们为旋转弦态的能量提供了大的$ j $ bmn型扩展，而振荡弦的旋转弦的能量则是在长字符串和小角度矩限制中得出的。
We study rigidly rotating and pulsating strings in the background of a 1+1 dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory by using the Neumann-Rosochatius (NR) model. Starting with the Polyakov action of the probe fundamental string we show that a generalised ansatz reduce the system into the one dimensional NR model in the presence of flux. The integrable construction of the model is exploited to analyze the rotating and oscillating string solution. We render the large $J$ BMN-type expansion for the energy of rotating string states while the same for the oscillating string has been derived in long string and small angular momenta limit.
