摘要:

本文研究了以非洛伦兹Kaplan-Moody(NLKM)代数为基础对称的二维量子场论.我们的调查包括二维伽利略(光速$c \rightarrow \infty$)和卡罗尔($c \rightarrow 0$)CFTs与额外数量的无限非阿贝尔电流,源于两个代数之间的同构。我们在内在分析和极限分析之间交替进行。我们的NLKM代数构造第一次通过收缩,然后从本质上Carrollian的角度。然后,我们继续使用对称性来推导非洛伦兹(NL)Sugawara结构,并最终写出Knizhnik Zamolodchikov方程的NL等价物。所有这些也来自收缩,从而提供了一个强大的交叉检查我们的分析。

英文摘要:

We investigate two dimensional (2d) quantum field theories which exhibit Non- Lorentzian Kač-Moody (NLKM) algebras as their underlying symmetry. Our investigations encompass both 2d Galilean (speed of light $c \rightarrow \infty$) and Carrollian ($c \rightarrow 0$) CFTs with additional number of infinite non-Abelian currents, stemming from an isomorphism between the two algebras. We alternate between an intrinsic and a limiting analysis. Our NLKM algebra is constructed first through a contraction and then derived from an intrinsically Carrollian perspective. We then go on to use the symmetries to derive a Non-Lorentzian (NL) Sugawara construction and ultimately write down the NL equivalent of the Knizhnik Zamolodchikov equations. All of these are also derived from contractions, thus providing a robust cross-check of our analyses.
