In this introductory review we discuss dynamical tests of the AdS5 × S5 string/[Formula: see text] Super Yang-Mills duality. After a brief introduction to AdS/CFT, we argue that semiclassical string energies yield information on the quantum spectrum of the string in the limit of large angular momenta on the S5. The energies of the folded and circular spinning string solutions rotating on a S3 within the S5 are derived, which yield all-loop predictions for the dual gauge theory scaling dimensions. These follow from the eigenvalues of the dilatation operator of [Formula: see text] Super Yang-Mills in a minimal SU(2) subsector, and we display its reformulation in terms of a Heisenberg s = 1/2 spin chain along with the coordinate Bethe ansatz for its explicit diagonalization. In order to make contact to the spinning string energies, we then study the thermodynamic limit of the one-loop gauge theory Bethe equations and demonstrate the matching with the folded and closed string result at this loop order. Finally, the known gauge theory results at higher-loop orders are reviewed and the associated long-range spin chain Bethe ansatz is introduced, leading to an asymptotic all-loop conjecture for the gauge theory Bethe equations. This uncovers discrepancies at the three-loop order between gauge theory scaling dimensions and string theory energies and the implications of this are discussed. Along the way, we comment on further developments and generalizations of the subject and point to the relevant literature.

AdS / CFT对应中的旋转字符串和可整合的旋转链。

在这篇介绍性综述中,我们讨论了AdS5×S5字符串/ [公式:参见文本] Super Yang-Mills对偶性的动态测试。在简要介绍AdS / CFT之后,我们认为半经典弦能量会在S5的大角动量极限内在弦的量子谱上产生信息。得出在S5内在S3上旋转的折叠和圆形纺丝线溶液的能量,从而得出双轨距理论定标尺寸的全回路预测。这些来自[SU](2)最小子扇区中[超级公式]的超级运算符的膨胀算符的特征值,我们根据Heisenberg s = 1/2自旋链及其坐标来显示其重新表示形式Bethe ansatz的显着对角线化效果。为了与纺丝线能量接触,然后,我们研究单回路规范理论Bethe方程的热力学极限,并证明在该回路顺序下与折叠和闭合弦结果相匹配。最后,回顾了已知的高环阶规范理论的结果,并引入了相关的远程自旋链Bethe ansatz,从而导致了规范理论Bethe方程的渐近全环猜想。这揭示了规范理论定标尺寸与弦理论能量之间的三环级差异,并对此进行了讨论。在此过程中,我们评论了该主题的进一步发展和概括,并指出了相关文献。回顾了已知的高环阶规范理论的结果,并介绍了相关的远程自旋链Bethe ansatz,从而得出了规范理论Bethe方程的渐近全环猜想。这揭示了规范理论定标尺寸与弦理论能量之间的三环级差异,并对此进行了讨论。在此过程中,我们评论了该主题的进一步发展和概括,并指出了相关文献。回顾了已知的高环阶规范理论的结果,并介绍了相关的远程自旋链Bethe ansatz,从而得出了规范理论Bethe方程的渐近全环猜想。这揭示了规范理论定标尺寸与弦理论能量之间的三环级差异,并对此进行了讨论。在此过程中,我们评论了该主题的进一步发展和概括,并指出了相关文献。这揭示了规范理论定标尺寸与弦理论能量之间的三环级差异,并对此进行了讨论。在此过程中,我们评论了该主题的进一步发展和概括,并指出了相关文献。这揭示了规范理论定标尺寸与弦理论能量之间的三环级差异,并对此进行了讨论。在此过程中,我们评论了该主题的进一步发展和概括,并指出了相关文献。
