Tunneling-based quantum devices with ultracold strongly interacting atoms
This event is part of the Condensed Matter Theory Seminar Series.
After briefly reviewing the use of ultracold atoms for the implementation of quantum devices, I present in the first part of the talk recent results on the Josephson dynamics of two superfluid ultracold fermionic gases weakly linked by a controllable barrier . In the second part I discuss weakly coupled Y-junctions of Tonks-Girardeau gases, showing recent results on the experimental realization of Y-geometries with holographic traps .
