Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

This paper reviews recent experimental and theoretical progress concerning many-body
phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling …

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 paper presents a review of the current state of the art in the research field of cold and
ultracold molecules. It serves as an introduction to the focus issue ofNew Journal of Physics …

The realization of superfluidity in a dilute gas of fermionic atoms, analogous to
superconductivity in metals, represents a long-standing goal of ultracold gas research. In …

We report on the Bose-Einstein condensation of more than 105 Li2 molecules in an optical
trap starting from a spin mixture of fermionic lithium atoms. During forced evaporative …

Magnetically tunable Feshbach resonances were employed to associate cold diatomic
molecules in a series of experiments involving both atomic Bose and two-spin-component …

We have observed Bose-Einstein condensation of molecules. When a spin mixture of
fermionic L i 6 atoms was evaporatively cooled in an optical dipole trap near a Feshbach …

Experimental realization of a quantum degenerate gas of molecules would provide access
to a wide range of phenomena in molecular and quantum sciences. However, the very …

We discuss the behavior of weakly bound bosonic dimers formed in a two-component cold
Fermi gas at a large positive scattering length a for the interspecies interaction. We find the …
