TL;DR: Feshbach resonances are the essential tool to control the interaction between atoms in ultracold quantum gases and have found numerous experimental applications, opening up the way to important breakthroughs as mentioned in this paper.

TL;DR: A review of photo-association spectroscopy at ultracold temperatures can be found in this article, where a sampling of results including the determination of scattering lengths, their control via optical Feshbach resonances, precision determinations of atomic lifetimes from molecular spectra, limits on photoassociation rates in a Bose-Einstein condensate, and briefly, production of cold molecules.

TL;DR: The role of the centrifugal barrier in the final collision channel in reducing the loss of atoms from the trap due to transitions induced by the magnetic dipole-dipole interaction is discussed.

TL;DR: The observed Feshbach resonances in an ultracold mixture of two fermionic species are interpreted using a simple asymptotic bound state model and full coupled channels calculations and unambiguously assigns the observed resonances to various s- and p-wave molecular states.
