#Schematic#diagram of a mixture of spin-up and spin-down lithium atoms confined to an array of one-dimensional tubes. The number of spin-up atoms (shown in blue) exceeds the number of spin-down atoms (orange). The mixture separates for high polarization (upper tube) into a partially polarized inner region surrounded by wings of spin-up atoms or for lower spin imbalance (lower tube) , into a partially polarized inner region with paired wings. At intermediate polarization (central tube) the whole cloud is partially polarized. via #scienceisbeauty@tumblr
