Adiabatic preparation of entangled, magnetically ordered states with cold bosons in optical lattices
Araceli Venegas-Gomez, Johannes Schachenmayer, Anton S. Buyskikh +3
We analyze a scheme for preparation of magnetically ordered states of two-component bosonic atoms in optical lattices. We compute the dynamics during adiabatic and optimized time-d…

Dynamics of rotated spin states and magnetic ordering with two-component bosonic atoms in optical lattices
Araceli Venegas-Gomez, Anton S. Buyskikh, Johannes Schachenmayer +2
The microscopic control available over cold atoms in optical lattices has opened new opportunities to study the properties of quantum spin models. While a lot of attention is focus…

Enhanced Superexchange in a Tilted Mott Insulator
Ivana Dimitrova, Niklas Jepsen, Anton Buyskikh +4
In an optical lattice entropy and mass transport by first-order tunneling is much faster than spin transport via superexchange. Here we show that adding a constant force (tilt) sup…
