研究了上半平面上的阿贝尔沙堆模型,并重新考虑了边界上四个高度变量的相关性。为了方便起见,我们在模型的耗散(质量)扩展中进行分析,并识别出四个高度对应的边界标度场。我们发现它们都可以用c=-2对数共形场理论的大量摄动来解释。评论:19页,3张图
We study the abelian sandpile model on the upper half plane, and reconsider the correlations of the four height variables lying on the boundary. For more convenience, we carry out the analysis in the dissipative (massive) extension of the model and identify the boundary scaling fields corresponding to the four heights. We find that they all can be accounted for by the massive pertubation of a c=-2 logarithmic conformal field theory. Comment: 19 pages, 3 figures
