Figure 1: (Left) A sketch of the one-dimensional order-parameter modulation in the FFLO state of organic superconductors, where the stripes correspond to different superconducting phases separated by magnetically ordered regions (blue). (Right) The two-dimensional polka-dot pattern proposed by Saunders, Parpia, and colleagues to explain nuclear magnetic resonance observations of superfluid helium-3 [1]. The domains here correspond to different superfluid phases (B+ and B−), which are separated by nonsuperfluid domain walls (blue).April 2019: Exotic behaviors emerge in atoms when cooled to near absolute zero, a temperature so cold that atoms cease their jittery movement. By bringing the isotope helium-3 to the brink of that threshold and confining it to a tiny space, KIC member Jeevak Parpia discovered that a surprising polka dot pattern spontaneously appeared in the superfluid.  Read the full story in the Cornell Chronicle.
