Sorna Prava Barik, Kamal L. Panigrahi

摘要:

研究了$AdS_3\times S^3$几何中刚性旋转弦和闭合折叠弦的有限尺寸效应。用Lambert $\mathbf{W}-$函数计算了无限大巨磁振子和单尖峰色散关系的经典指数修正。我们还以Lambert $\mathbf{W}-$函数的形式给出了有限长Gubser-Klebanov-Polyakov(GKP)弦色散关系的解析表达式。

英文摘要:

We study the finite size effect of rigidly rotating strings and closed folded strings in $AdS_3\times S^3$ geometry with NS-NS B-field. We calculate the classical exponential corrections to the dispersion relation of infinite size giant magnon and single spike in terms of Lambert $\mathbf{W}-$function. We also write the analytic expression for the dispersion relation of finite size Gubser-Klebanov-Polyakov (GKP) string in the form of Lambert $\mathbf{W}-$function.
