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

An overview of the physics of spinor and dipolar Bose–Einstein condensates (BECs) is
given. Mean-field ground states, Bogoliubov spectra, and many-body ground and excited …

This paper describes program LEVEL, which can solve the radial or one-dimensional
Schrödinger equation and automatically locate either all of, or a selected number of, the …

Photoassociation is the process in which two colliding atoms absorb a photon to form an
excited molecule. The development of laser-cooling techniques for producing gases at …

Bose-Einstein condensates of sodium atoms have been prepared in optical and magnetic
traps in which the energy-level spacing in one or two dimensions exceeds the interaction …

The description of an impurity atom in a Bose-Einstein condensate can be cast in the form of
Fröhlich's polaron Hamiltonian, where the Bogoliubov excitations play the role of the …

We propose new experiments with high sensitivity to a possible variation of the electron-to-
proton mass ratio μ≡ me/mp. We consider a nearly degenerate pair of molecular vibrational …

This book presents a concise and modern coverage of scattering theory. It is motivated by
the fact that experimental advances have shifted and broadened the scope of applications …

We consider the problem of cold atomic collisions in tight traps, where the absolute
scattering length may be larger than the trap size. As long as the size of the trap ground state …

We form ultracold Na 2 molecules by single-photon photoassociation of a Bose-Einstein
condensate, measuring the photoassociation rate, linewidth, and light shift of the J= 1, v …
