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 …

Gauge fields are central in our modern understanding of physics at all scales. At the highest
energy scales known, the microscopic universe is governed by particles interacting with …

The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

Gamma-ray bursts (GRB's), short and intense pulses of low-energy γ rays, have fascinated
astronomers and astrophysicists since their unexpected discovery in the late sixties. During …

We have observed condensation of fermionic atom pairs in the BCS-BEC crossover regime.
A trapped gas of fermionic K 40 atoms is evaporatively cooled to quantum degeneracy and …

Strongly correlated quantum systems are among the most intriguing and fundamental
systems in physics. One such example is the Tonks–Girardeau gas,, proposed about 40 …

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 …

Heat engines convert thermal energy into mechanical work both in the classical and
quantum regimes. However, quantum theory offers genuine non-classical forms of energy …

We have observed Bose-Einstein condensation of pairs of fermionic atoms in an ultracold Li
