我们研究了3×S_1上=4SUSY杨-Mills理论在弱耦合和强耦合条件下去禁闭相中的磁化壁张量。我们计算了单圈阶下的k壁张力，发现它与k(N−k)(Casimir标度)成正比。双环分析表明，Casimir标度遵循这个顺序。强耦合计算采用ADS/CFT对应关系。我们认为，在IIB型弦理论的AdS-Schwarzschild×S5背景中，k-壁应该被认为是包裹着S4的NS5-膜。将强耦合时的张力与弱耦合时的结果进行了比较。我们还将我们的结果与纯杨-米尔斯理论中的晶格模拟结果进行了比较。
We study the tensions of domain walls in the deconfined phase of = 4 SUSY Yang-Mills theory on 3 × S1, at weak and strong coupling. We calculate the k-wall tension at one-loop order and find that it is proportional to k(N−k) (Casimir scaling). The two-loops analysis suggests that Casimir scaling persists to this order. The strong coupling calculation is performed by using the AdS/CFT correspondence. We argue that the k-wall should be identified with an NS5-brane wrapping an S4 inside S5 in the AdS-Schwarzschild × S5 background in Type IIB string theory. The tension at strong coupling is compared with the weak coupling result. We also compare our results with those from lattice simulations in pure Yang-Mills theory.
