    "abstract": "We show that by displacing two optical lattices with respect to each other,\nwe may produce interactions similar to the ones describing ferro-magnetism in\ncondensed matter physics. We also show that particularly simple choices of the\ninteraction lead to spin-squeezing, which may be used to improve the\nsensitivity of atomic clocks. Spin-squeezing is generated even with partially,\nand randomly, filled lattices, and our proposal may be implemented with current\ntechnology.",
