简介:超导性(SC)或superfluidity(SF)越过fermionic系统的一个显著地宽广的范围被观察:在英国计算机学会,cuprate,基于铁、器官、重费米子的超导体,并且在在压缩物质的超流体helium-3;在在低精力的核物理学的许多SC/SF现象;在ultracold,套住原子气体;并且在在中子的各种各样的异国情调的可能性担任主角。在显微镜的物理的物理条件和差别的范围对抗所有尝试在任何常规图画统一这行为。这里,我们通过突现的压缩状态的分享的对称性质建议统一,与吸收进参数的显微镜的差别。接着,这强迫一象被称为在cuprates的cSC,它成为远更少神秘什么时候作为行为的连续统的部分看,分享了由许多另外的系统。
