我们表明,1+ 1维因果动态三角剖分(CDT)耦合到4个大质量标量场,可以构建一个有效的传输矩阵,如果质量平方大于或等于0.05。这个传递矩阵的性质可以解释为什么耦合到物质的CDT可以表现出与“纯”CDT完全不同的行为。我们确定了有效作用中的重要临界指数,它可能决定了模型的普适类。
We show that for 1+ 1 dimensional Causal Dynamical Triangulations (CDT) coupled to 4 massive scalar fields one can construct an effective transfer matrix if the masses squared are larger than or equal to 0.05. The properties of this transfer matrix can explain why CDT coupled to matter can behave completely different from “pure” CDT. We identify the important critical exponent in the effective action, which may determine the universality class of the model.
