Részletes információ (tartalmi kivonat):
    <p>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.</p>
<p>The presentation is planned to be a tutorial, and we will try to 
understand the analogy between Josephson junctions of SIS layers and the 
bosonic BEC double well systems.</p>
