The effect of a laser dip in the semiclassical dynamics of bosonic Josephson Junctions

Abstract

We consider the standard double well setup extended with a laser beam in the center to create a "triple well" potential. The beam in the center is much more narrow than the barrier, and it creates a tunable depth well which can support a localized state in the middle. We show that the presence of the localized state in the central well changes the sign of tunneling between the left and right wells and therefore controls the fixed point dynamics of the bosonic Josephson junction.
