作为普遍涌现现象的超导性和超流性

Superconductivity and Superfluidity as Universal Emergent Phenomena

Mike Guidry, Yang Sun

摘要:

超导性(SC)或超流性(SF)在非常广泛的费米子系统中被观察到:在BCS,铜酸盐,铁基,有机和重费米子超导体中,以及凝聚态中的超流氦-3;在低能核物理中的各种SC/SF现象中;在超冷,捕获的原子气体中;以及在中子星中的各种奇异可能性中。物理条件的范围和微观物理学的差异使所有试图将这种行为统一在任何传统图像中的尝试都失败了。在这里,我们提出了一个统一的紧急凝聚态,通过共享的对称性,吸收到参数的微观差异。这反过来又迫使人们重新思考SC/SF的特定事件,例如铜酸盐高温超导性,当被视为各种其他系统共享的连续行为的一部分时,它变得不那么神秘。

英文摘要:

Superconductivity (SC) or superfluidity (SF) is observed across a remarkably broad range of fermionic systems: in BCS, cuprate, iron-based, organic, and heavy-fermion superconductors, and superfluid helium-3 in condensed matter; in a variety of SC/SF phenomena in low-energy nuclear physics; in ultracold, trapped atomic gases; and in various exotic possibilities in neutron stars. The range of physical conditions and differences in microscopic physics defy all attempts to unify this behavior in any conventional picture. Here we propose a unification through the shared symmetry properties of the emergent condensed states, with microscopic differences absorbed into parameters. This, in turn, forces a rethinking of specific occurrences of SC/SF such as cuprate high-temperature superconductivity, which becomes far less mysterious when seen as part of a continuum of behavior shared by a variety of other systems.
