Landau-Zener Sweeps and Sudden Quenches in Coupled Bose-Hubbard Chains
Landau-Zener Sweeps and Sudden Quenches in Coupled Bose-Hubbard Chains
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 in the leg with higher energy, we find a drastic reduction of the inter-chain particle transfer for slow linear sweeps, in quantitative …
