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…
Treelike interactions and fast scrambling with cold atoms
Gregory Bentsen, Tomohiro Hashizume, Anton S. Buyskikh +4
We propose an experimentally realizable quantum spin model that exhibits fast scrambling, based on non-local interactions which couple sites whose separation is a power of 2. By co…
Resonant two-site tunnelling dynamics of bosons in a tilted optical superlattice
Anton S. Buyskikh, Luca Tagliacozzo, Dirk Schuricht +3
We study the non-equilibrium dynamics of a 1D Bose-Hubbard model in a gradient potential and a superlattice, beginning from a deep Mott insulator regime with an average filling of…
Spin-models, dynamics and criticality with atoms in tilted optical superlattices
Anton S. Buyskikh, Luca Tagliacozzo, Dirk Schuricht +3
We show that atoms in tilted optical superlattices provide a platform for exploring coupled spin chains of forms that are not present in other systems. In particular, using a perio…
