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…

David Wellnitz, Stefan Schütz, Shannon Whitlock +2
We propose a mechanism to realize high-yield molecular formation from ultracold atoms. Atom pairs are continuously excited by a laser, and a collective decay into the molecular gro…

Anton S. Buyskikh, Maurizio Fagotti, Johannes Schachenmayer +2
We investigate the dynamics following a global parameter quench for two 1D models with variable-range power-law interactions: a long-range transverse Ising model, which has recentl…

We study the out-of-equilibrium dynamics of bosonic atoms in a 1D optical lattice, after the ground-state is excited by a single spontaneous emission event, i.e. after an absorptio…
