E/T scaling and quantum critical fluctuations in Sr3Ru2O7

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....诸多新奇的电子基态会在量子临界点（quantum critical points, QCPs）附近形成，量子临界点即为零温度下发生连续相变的临界位置。
