AI总结:

本文构造二维边界卡罗尔共形代数,证明其可由 Virasoro 代数收缩得到,并首次构造开零弦,在 Dirichlet 边界条件下恢复该代数作为约束代数。

摘要:

我们考虑二维卡罗尔共形场论,并构造边界卡罗尔共形代数(BCCA),鉴于卡罗尔对称性日益增长的重要性,这为进一步研究开辟了无数可能性。我们证明,BCCA 是通过收缩 Virasoro 代数的单个副本而涌现的。作为一个应用,我们首次构造了开零弦,并证明在 Dirichlet 边界条件下,我们恢复出 BCCA 作为约束代数。最后,我们通过取有张力开弦的零极限来重建我们的弦论结果。

英文摘要:

We consider Carrollian conformal field theories in two dimensions and construct the boundary Carrollian conformal algebra (BCCA), opening up innumerable possibilities for further studies, given the growing relevance of Carrollian symmetries. We prove that the BCCA emerges by contracting a single copy of the Virasoro algebra. As an application, we construct, for the first time, open null strings and show that, for Dirichlet boundary conditions, we recover the BCCA as the algebra of constraints. We finally reconstruct our string results by taking the null limit of tensile open strings.
