  • Nearly forty years ago, Fulde, Ferrell, Larkin and Ovchinnikov (FFLO) proposed an exotic theory of polarized superconductivity. FFLO correlations have never been observed, but it is thought that in one dimension (1D) a state with FFLO correlations occupies a major part of the phase diagram. Now, intriguing measurements are reported of the phase profile of a two-spin mixture of ultracold 6Li atoms trapped in an array of 1D tubes. The findings may provide a hint of FFLO physics.
