AdS3中的旋转威尔逊圈和开弦

Rotating Wilson loops and open strings in AdS3

Andrew Irrgang, Martin Kruczenski

摘要:

AdS/CFT对应将S3上的N=4超级杨米尔斯与AdS 5 xS 5上的IIB型弦论联系起来。在这种情况下,一个夸克/反夸克对在S3内部的S1上沿着预定的轨迹运动,它与一个终止于AdS 3边界的开弦是对偶的。本文研究了相应的经典弦解。Pohlmeyer简化将运动方程简化为广义sinh-Gordon方程。这个方程包括,作为特殊情况下,刘维方程以及sinh/cosh-Gordon方程。我们研究了Liouville方程的通解和sinh/cosh-Gordon方程的有限间隙解。后者是写在黎曼θ函数。相应的字符串的解决方案进行重建,给出新的解决方案和广泛的理解,在AdS 3中移动的开弦。作为进一步的例子,一个简单的情况下,刚性旋转的字符串显示出这三个行为取决于一个简单的关系,它的角速度和它的端点之间的角间距。

英文摘要:

The AdS/CFT correspondence relates N=4 super Yang-Mills on S3 to type IIB string theory on AdS5xS5. In this context, a quark/anti-quark pair moving on an S1 inside S3 following prescribed trajectories is dual to an open string ending on the boundary of AdS3. In this paper we study the corresponding classical string solutions. The Pohlmeyer reduction reduces the equations of motion to a generalized sinh-Gordon equation. This equation includes, as particular cases, the Liouville equation as well as the sinh/cosh-Gordon equations. We study generic solutions of the Liouville equation and finite gap solutions of the sinh/cosh-Gordon ones. The latter ones are written in terms of Riemann theta functions. The corresponding string solutions are reconstructed giving new solutions and a broad understanding of open strings moving in AdS3. As a further example, the simple case of a rigidly rotating string is shown to exhibit these three behaviors depending on a simple relation between its angular velocity and the angular separation between its endpoints.
