Tunneling resonances and entanglement dynamics of cold bosons in the double well
Dimitri R. Dounas-Frazer, Lincoln D. Carr
We present exact expressions for the quantum sloshing of ultracold bosons in a tilted two-well potential. Tunneling is suppressed by a small potential difference between wells, or tilt. However, tunneling resonances occur for critical values of the tilt when the barrier is high. At resonance, tunneling times on the order of 10-100 ms are possible. Furthermore, tunneling resonances constitute a dynamic scheme for creating robust few-atom entangled states in the presence of many bosons.
