Low-energy fluctuations on approaching the structural quantum critical point ...

Quantum critical points (QCPs) are second order phase transitions that occur at T=0; they involve unusual critical fluctuations, which give rise to interesting phenomena such as...量子临界点（Quantum Critical Points, QCPs）是发生于绝对零度（T=0）下的二级相变；这类相变存在反常的临界涨落，由此会产生诸如……等一系列有趣的物理现象。
