Recent studies of Feshbach resonance in the field of Bose-Einstein condensation

Feshbach resonance is currently a very hot topic in the area of Bose-Einstein condensation, and has already been observed in most low-temperature alkali gases. In these systems the interaction between atoms con be tuned from strong repulsion to strong attraction. A detailed overview is given of the Feshbach resonance and two of its most important aspects, the superfluid phase in Fermi gases and the strong-interaction regime in Bose gases
