薛定谔几何经典弦解的有限尺寸效应

Finite size effects in classical string solutions of the Schrodinger geometry

Dimitrios Zoakos

摘要:

我们研究薛定谔时空的半经典弦解的有限尺寸修正。我们计算了单自旋巨磁振子和单自旋单尖峰解的无限尺寸色散关系的首阶指数修正。该解存在于五球的$S^3$子空间中,并在度规的薛定谔部分中延伸。在零变形极限,有限尺寸色散关系流到未变形的$AdS_5 \times S^5$对应物,在无限尺寸极限,修正项消失,得到已知的无限尺寸色散关系。

英文摘要:

We study finite size corrections to the semiclassical string solutions of the Schrodinger spacetime. We compute the leading order exponential corrections to the infinite size dispersion relation of the single spin giant magnon and of the single spin single spike solutions. The solutions live in a $S^3$ subspace of the five-sphere and extent in the Schrodinger part of the metric. In the limit of zero deformation the finite size dispersion relations flow to the undeformed $AdS_5 \times S^5$ counterparts and in the infinite size limit the correction term vanishes and the known infinite size dispersion relations are obtained.
