Constantin Candu, Hubert Saleur

摘要:

本文基于本文中介绍的格点正则化方法,研究了环上边界$OSp(2S+2|2S)$陪集西格玛模型的配分函数。利用$OSp(2S+2|2S)$和$B_L(2)$对相应自旋链作用的结果,以及小超空间和小$g_σ^2$计算,我们推测了整个临界线上的全谱和简并集。讨论了与$OSp(2S+2|2S)$ Gross-Neveu模型的潜在联系。

英文摘要:

We consider the partition function of the boundary $OSp(2S+2|2S)$ coset sigma model on an annulus, based on the lattice regularization introduced in the companion paper. Using results for the action of $OSp(2S+2|2S)$ and $B_L(2)$ on the corresponding spin chain, as well as mini-superspace and small $g_σ^2$ calculations, we conjecture the full spectrum and set of degeneracies on the entire critical line. Potential relationship with the $OSp(2S+2|2S)$ Gross-Neveu model is also discussed.
