Atomtronics deals with matter-wave circuits of ultracold atoms manipulated through
magnetic or laser-generated guides with different shapes and intensities. In this way, new …

This report addresses topics and questions of common interest in the fields of ultra-cold
gases and nuclear physics in the context of the BCS–BEC crossover. By this crossover, the …

Persistent currents in annular geometries have played an important role in disclosing the
quantum phase coherence of superconductors and mesoscopic electronic systems …

After decades of improvements in cooling techniques of several atomic species and in
finding methods for the achievement of stable quantum mixtures, the field is now ready for …

In recent years, the ability of cold atom experiments to explore condensed-matter-related
questions has dramatically progressed. Transport experiments, in particular, have expanded …

Ultracold atomic gases are a powerful tool to experimentally study strongly correlated
quantum many-body systems. In particular, ultracold Fermi gases with tunable interactions …

We report on the experimental realization of homogeneous two-dimensional (2D) Fermi
gases trapped in a box potential. In contrast to harmonically trapped gases, these …

We have produced persistent currents of ultracold fermionic atoms trapped in a ring, with
lifetimes greater than 10 sec in the strongly interacting regime. These currents remain stable …

The role of reduced dimensionality in high-temperature superconductors is still under
debate. Recently, ultracold atoms have emerged as an ideal model system to study such …

The Josephson effect is a macroscopic quantum phenomenon that reveals the broken
symmetry associated with any superfluid state. Here we report on the observation of the …
