仅具有 Virasoro 对称性的二维共形场理论具有可积结构。我们回顾了如何在二维共形场理论中构造可积电荷,以及当 c ≥ 25 时如何将它们与量子 Sinh-Gordon 理论的电荷联系起来。然后,我们明确计算所有电荷的大 c 限制中的单电荷特征,从而揭示它们的简并性如何在一个模块内增长。特别是,这使我们能够在小化学势的限制下近似特征,这些化学势是各自电荷的来源。后者让我们深入了解角色可能的变形属性。我们还评论了完整的广义吉布斯系综和纯态的近似。
Two-dimensional conformal field theories with just Virasoro symmetry are endowed with integrable structure. We review how to construct the integrable charges in a two-dimensional conformal field theory and how to relate them to the charges of quantum Sinh-Gordon theory when c ≥ 25 . We then explicitly calculate the single charge characters in the large c limit for all charges and thereby reveal how their degeneracies grow within one module. This, in particular, allows us to approximate the characters in the limit of small chemical potential, which source the respective charges. The latter give us insights into possible transformation properties of the characters. We also comment on the full generalized Gibbs ensemble and approximations to pure states.
