DESCRIPTION:Speaker: Andrea Trombettoni\nhosted by Giacomo Bighin / Lemeshk
 o Group\nAbstract: After briefly reviewing the use of ultracold atoms for 
 the implementation of quantum devices\, I discuss two examples of junction
 s made by strongly interacting systems weakly coupled between them. I pres
 ent in the first part of the talk recent results on the Josephson dynamics
  of two ultracold fermionic gases at the unitary limit weakly linked by a 
 controllable barrier. In the second part I discuss properties of 1D Bose g
 ases and then of junctions of Tonks-Girardeau gases. When three Tonks-Gira
 rdeau gases are coupled\, one can exactly map their Hamiltonian by means o
 f a suitable Jordan-Wigner transformation into the Hamiltonian of the mult
 ichannel Kondo model. I will also show recent results on the experimental 
 realization of Y-geometries with holographic traps\, and comment about rec
 ent progress in atomtronics.
