摘要
量子 critical behavior occurs when a material is near a zero temperature 相變 between two ordered forms of matter. Kondo lattice materials, in which itinerant heavy (∼200 bare mass) electrons emerge through the collective hybridization of localized f electrons with background conduction electrons, provide a rich source of experimental 資訊 about how, for example, pressure and magnetic fields influence local moment antiferromagnetic order and its boundary with competing fully itinerant heavy electron behavior in the pressure–magnetic field plane. A phenomenological two-fluid model of coupled local moments and itinerant heavy electrons enables us to calculate both and obtain a quantitative account of related 量子 critical behavior in two of the best-studied heavy electron materials, CeCoIn5 and YbRh
