Superconductivity and superfluidity as universal emergent phenomena

Abstract: 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 … Show more

“…As pointed out by Anderson in his treatise, More is Different , 'the whole becomes not only more than but very different from the sum of its parts' [70]. The appearance of zeroviscosity in superfluids, zero resistivity in superconducting metals, and magnetism are all examples of simple behaviors that arise, not from detailed microscopic forces, but from the emergence of collective organizational phenomena [71][72][73]. These phenomena depend on powerful and general principles of organization that, while they are not generally understood, can provide great insight into macroscopic collective behavior [73,74].…”

“…shows that phase diagrams for unconventional SC emergent states in a broad range of condensed matter systems and in nuclear structure are remarkably similar, despite completely different microscopic physics (see Refs. [33,40] for further discussion). An even more remarkable universality of emergent states is shown in the coherent state energy surfaces displayed in Figure 8.…”

“…The corresponding emergent states are not related perturbatively to the parent state. Therefore, in understanding such properties, we cannot focus on microscopic properties of the normal state, as the transition from the microscopic parent state to the collective emergent state is not analytic [ 15 ]. To quote Anderson’s words, “the whole is not only greater than but very different from the sum of the parts” [ 16 ].…”
