我们研究了奇数维超球体上主手性模型 (PCM) 的谱作为曲率半径 R 的函数。对于 S 3|2 上的体积填充膜,我们计算了作为 R 函数的精确边界谱。讨论了向更高维超球体的扩展,但没有详细进行。我们的结果提供了非常令人信服的证据,支持 Candu 和 Saleur 最近推测的超球面 PCM 和 OSP(2S+2|2S) Gross-Neveu 模型之间的强弱耦合对偶性。
We investigate the spectrum of the principal chiral model (PCM) on odd- dimensional superspheres as a function of the curvature radius R. For volume-filling branes on S 3|2 , we compute the exact boundary spectrum as a function of R. The extension to higher dimensional superspheres is discussed, but not carried out in detail. Our results provide very convincing evidence in favor of the strong-weak coupling duality between supersphere PCMs and OSP(2S+2|2S) Gross-Neveu models that was recently conjectured by Candu and Saleur.
