Atomtronics with strongly correlated bosons and fermions on a ring
Quantum many-body systems are challenging since more half a century theorists and experimentalists.  The understanding of their arbitrary quantum dynamics remains one among the major open question. In this talk I will address  this question for a specific quantum system, made of ultracold atoms flowing into a ring-shaped tight waveguide, in the regime where quantum correlation effects take place. I will describe how to implement and read-out a persistent current flow, and  how to probe its stability against thermal and quantum phase slips, discussing the specific differences for bosonic and fermionic particles. Our results could find application in quantum technologies,  eg to quantum-enhanced rotation sensors.
