标题： Grand-Canonical simulation of 4D simplicial quantum gravity

摘要： 对4D量子引力（QG）场论的全面数值研究，特别强调共形模式依赖性已被研究。比以往更清晰的是，我们通过使用大正则蒙特卡洛方法获得了配分函数的弦易感指数。仔细考虑更新方法，模拟是在4D欧几里得单纯流形耦合到$N_X$标量场和$N_A$U(1) 规范场的情况下进行的。数值结果表明，4D单纯量子引力（SQG）可以达到4D QG的连续理论。我们讨论了4D SQG的重要性质。 显示英文摘要

摘要： A thorough numerical examination for the field theory of 4D quantum gravity (QG) with a special emphasis on the conformal mode dependence has been studied. More clearly than before, we obtain the string susceptibility exponent of the partition function by using the Grand-Canonical Monte-Carlo method. Taking thorough care of the update method, the simulation is made for 4D Euclidean simplicial manifold coupled to $N_X$ scalar fields and $N_A$ U(1) gauge fields. The numerical results suggest that 4D simplicial quantum gravity (SQG) can be reached to the continuum theory of 4D QG. We discuss the significant property of 4D SQG.
