Description
Many analogies exist between nanostructured quantum systems such as quantum dots, and trapped ultra-cold atom gases. The newly emerging "atomtronics" makes phenomena such as Bose-Einstein condensation accessible for the micro- and nano-design of future quantum devices.
In this talk, we shall discuss how effects similar to Coulomb blockade in quantum dots may occur in systems of ultracold, trapped atoms [1-3].
We furthermore comment on vortices in single- and multi-component systems and point out the analogies between bosonic and fermionic quantum gases set rotating [4-6].
