论文摘要
我们研究了在四维因果动力学三角形（CDT）中观察到的阶段$ b $和$ c_b $之间的过渡。我们发现，带有环形空间拓扑的CDT的临界特性与在球形空间拓扑中观察到的早期相同，在球形空间拓扑中，发现$ b-c_b $ transition被发现是高阶。这可能会对CDT的连续限制的存在产生重要影响，描述了量子重力的透视量极限，这可能会在环形模型中进行研究。
We investigate the transition between the phases $B$ and $C_b$ observed in four-dimensional Causal Dynamical Triangulations (CDT). We find that the critical properties of CDT with toroidal spatial topology are the same as earlier observed in spherical spatial topology where the $B-C_b$ transition was found to be higher-order. This may have important consequences for the existence of the continuum limit of CDT, describing the perspective UV limit of quantum gravity, which potentially can be investigated in the toroidal model.
