Landau-Zener sweeps and sudden quenches in coupled Bose-Hubbard chains
Christian Kasztelan, Stefan Trotzky, Yu-Ao Chen +4
We simulate numerically the dynamics of strongly correlated bosons in a two-leg ladder subject to a time-dependent energy bias between the two chains. When all atoms are initially…
Magnetism, coherent many-particle dynamics, and relaxation with ultracold bosons in optical superlattices
Thomas Barthel, Christian Kasztelan, Ian P. McCulloch +1
We study how well magnetic models can be implemented with ultracold bosonic atoms of two different hyperfine states in an optical superlattice. The system is captured by a two-spec…
A Factorization Law for Entanglement Decay
Thomas Konrad, Fernando de Melo, Markus Tiersch +3
We present a simple and general factorization law for quantum systems shared by two parties, which describes the time evolution of entanglement upon passage of either component thr…
