摘要：

An attempt is made to illustrate that the mapping to a classical lattice system brings a more fundamental definition of phase transition, and consequently, other tools to find the transition points. In particular, it is shown that the classical lattice mapping using Feyman's path integral has a known scaling behavior when the principle is free.
