关于$AdS_3 \times S^3 \times T^4$的量子形变和镜像对偶

On quantum deformations of $AdS_3 \times S^3 \times T^4$ and mirror duality

Fiona K. Seibold, Stijn J. van Tongeren, Yannik Zimmermann

摘要:

本文研究了具有量子群对称性的$AdS_3 \times S^3 \times T^4$超弦的各种可积双参数形变。在光锥规范的弦世界表和费米子的二次阶下,我们得到了它们共同的有质量树级二体S矩阵,它与严格的$q$变形S矩阵的展开相匹配.然后,我们分析的行为下镜像变换的确切S矩阵-一个双威克旋转的世界表-并发现,它满足镜像对偶关系类似于著名的$q$ -变形$AdS_5 \times S^5$ S矩阵的一个参数的变形限制。最后,我们证明了费米子$q$变形的$AdS_5 \times S^5$ S矩阵也满足这样的关系.

英文摘要:

We consider various integrable two-parameter deformations of the $AdS_3 \times S^3 \times T^4$ superstring with quantum group symmetry. Working on the string worldsheet in light-cone gauge and to quadratic order in fermions, we obtain their common massive tree-level two-body S matrix, which matches the expansion of the conjectured exact $q$-deformed S matrix. We then analyze the behavior of the exact S matrix under mirror transformation -- a double Wick rotation on the worldsheet -- and find that it satisfies a mirror duality relation analogous to the distinguished $q$-deformed $AdS_5 \times S^5$ S matrix in the one parameter deformation limit. Finally, we show that the fermionic $q$-deformed $AdS_5 \times S^5$ S matrix also satisfies such a relation.
