Superfluidity of quantum gases

In these lectures I will discuss the most relevant advances in the study of superfluid phenomena in ultra cold quantum gases. The presentation will include both theoretical and experimental aspects of superfluidity in Bose and Fermi gases, including a discussion of recent topics, like the superfluid behavior of coherently coupled Bose-Einstein condensed gases and of supersolid dipolar atomic gases.

1)  The Birth and Death of Matter Wave Solitons:  Bose-Einstein Condensates with Attraction

I will discuss the formation of matter wave solitons by quenching the interactions between atoms in Bose-Einstein condensates from repulsive to attraction.  The resulting instability can result in the creation of a train of solitons, each equally spaced.  A defining feature of solitons is that they pass through one another, but under certain circumstances they may merge or annihilate each other.

2) Quantum Magnetism of Atoms on an Optical Lattice

We show that a spin-1/2 Fermi atomic gas on an optical lattice can develop anti-ferromagnetic order when the lattice parameters, interaction and tunneling strength, are appropriately tuned, and when the temperature is sufficiently low.  This is an example of quantum simulation.  I will discuss how it may be possible to simulate high-temperature superconductors using cold atoms, thus addressing major questions about the essential mechanisms responsible for pairing in these exotic materials.
