Abstract

Polarized superconductivity: in search of FFLO More than 40 years ago, Fulde and Ferrell, at the same time as Larkin and Ovchinnikov, proposed an exotic theory of polarized superconductivity. Known as the FFLO state after these four authors, it has proved an elusive quarry. FFLO correlations have never been observed, but are thought to be most prevalent in the phase diagram of one-dimensional systems. Yean-an Liao et al. now report an experimental hint of the FFLO phase in measurements of the phase profile of a two-spin mixture of ultracold lithium-6 atoms trapped in an array of one-dimensional tubes.
