Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

This review is concerned with the physics and chemistry associated with the interactions,
collisions, and reactions of ultracold molecules, that is, molecules having translational …

An electron gas in a one-dimensional periodic potential can be transported even in the
absence of a voltage bias if the potential is slowly and periodically modulated in time …

Spin-exchanging interactions govern the properties of strongly correlated electron systems
such as many magnetic materials. When orbital degrees of freedom are present, spin …

We review recent experimental and theoretical progress on ultracold alkaline-earth Fermi
gases with emergent SU (N) symmetry. Emphasis is placed on describing the ground …

The Hubbard model accounts for many of the diverse phenomena observed in solid-state
materials, despite incorporating only nearest-neighbour hopping and on-site interactions for …

We report on the experimental observation of a novel interorbital Feshbach resonance in
ultracold Yb 173 atoms. This opens up the possibility of tuning the interactions between the …

We report the realization of a novel degenerate Fermi mixture with an SU (2)× SU (6)
symmetry in a cold atomic gas. We successfully cool the mixture of the two fermionic …

It is argued that an ultracold quantum degenerate gas of ytterbium 173 Yb atoms having
nuclear spin I= 5/2 exhibits an enlarged SU (6) symmetry. Within the Landau Fermi liquid …

We experimentally investigate an optical clock based on Yb 171 (I= 1/2) atoms confined in
an optical lattice. We have evaluated all known frequency shifts to the clock transition …
