Magnetic order in the quantum critical phase of 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，而量子临界点正是零温下发生连续相变的临界点。
