Recently, it was discovered that, near the quantum critical point the QPT system possesses the ultra-sensitivity in its dynamical evolution.

最近，人们发现对于一个量子相变系统，在它的临界点附近，量子相变系统的动力学具有极高的敏感性。

The quantum phase transition (QPT) occurs at zero temperature when the external parameters of some interacting many-body systems change to reach the critical values.

在许多多体量子系统中，随着系统某些外部参数达到它的临界值，在零温情况下量子系统会发生量子相变。
