Ultracold atoms in ring traps: from fundamentals to atomtronics applications
Anna Minguzzi
Abstract
Atomtronics is an emerging field that aims to manipulate ultracold atom moving in matter-wave circuits for fundamental studies in both quantum science and technological applications.I will present the principles of persistent currents for atoms subjected to artificial gauge fields. For the case of a tight transverse confinement, where the system is effectively one-dimensional, I will detail the theoretical models we use to account for the effects of interactions, from weak to strong. I will then present our results on the persistent currents for both bosons and multi-component Fermi gases, as well as the readout protocols envisaged. Finally, I will discuss possible applications to quantum technologies.
