Spin fluctuations near the quantumcritical point in La2-xSrxCuO4

Quantum critical points (QCP) can be detected through measurement of the specific heat and entropy. It has been proposed that there may be such a QCP at critical doping p in...量子临界点（Quantum critical points, QCP）可通过测量比热容与熵进行检测。已有研究提出，在临界掺杂浓度p处的……中可能存在此类量子临界点。
