微扰共形场论中缺陷的非定域守恒电荷

Non-local conserved charges from defects in perturbed conformal field theory

Ingo Runkel

摘要:

用(1,3)主体场扰动Virasoro极小模型得到可积场论。本文通过考虑缺陷,得到了可交换守恒荷的无限集合:给出了一类单参数的扰动缺陷算子族,证明了这些算子相互可交换,与扰动CFT的Hamilton算子可交换,并且满足T-系统函数关系.扰动缺陷的提法是对Bazhanov、Lukyanov和Zamolodchikov关于这种电荷的原始规定的修改。

英文摘要:

Perturbing a Virasoro minimal model by the (1,3) primary bulk field results in an integrable field theory. In this paper, an infinite set of commuting conserved charges is obtained by considering defects: a one-parameter family of perturbed defect operators is given, and it is shown that these operators mutually commute, that they commute with the Hamiltonian of the perturbed CFT, and that they satisfy a T-system functional relation. The formulation in terms of perturbed defects is a modification of the original prescription for such charges by Bazhanov, Lukyanov and Zamolodchikov.
