论文摘要
我们在量子系统的连续时间蒙特卡洛模拟中实施蒙特卡洛重新归一化组(MCRG)。我们从数值上证明了在量子关键时表现出Lorentz不变性的系统的空间和时间之间的新兴各向同性。这使我们能够准确估计这些量子系统的声速。 $ Q $ - 状态POTTS模型在一个和两个空间维度中用于说明该方法。
We implement Monte Carlo Renormalization Group (MCRG) in the continuous-time Monte Carlo simulation of a quantum system. We demonstrate numerically the emergent isotropy between space and time at large distances for the systems that exhibit Lorentz invariance at quantum criticality. This allows us to estimate accurately the sound velocity for these quantum systems. $Q$-state Potts models in one and two space dimensions are used to illustrate the method.
