铁基超导体的量子临界行为∗OA北大核心CSCDCSTPCD

In the past several decades, quantum phase transition and the associated fluctuations have emerged as a major challenge to our understanding of condensed matter. Such transition is tuned by an external parameter such as pressure, chemical doping or magnetic field. The transition point, called quantum critical point (QCP), is only present at absolute zero temperature (T ), but its influence (quantum criticality) is spread to nonzero temperature region. Quite …查看全部>>
