Enhanced Superexchange in a Tilted Mott Insulator

Enhanced Superexchange in a Tilted Mott Insulator

In an optical lattice, entropy and mass transport by first-order tunneling are much faster than spin transport via superexchange. Here we show that adding a constant force (tilt) suppresses first-order tunneling, but not spin transport, realizing new features for spin Hamiltonians. Suppression of th...
