Abstract

The observation of Bose–Einstein condensation (BEC) in atomic gases [1–3] has changed the paradigm of chemical physics (or atomic, molecular, and optical physics, in brief, AMO) with the birth of a new field: ultracold physics (see Fig. 3.1). Therefore, we believe that we should provide a basic, but necessary, introduction to the physics of ultracold gases to pave the way for ultracold chemistry.

Notes

  1. 1.

    This is the same effective potential that Fermi derived for a Rydberg electron colliding with a neutral atom (but taking into account that for the BEC problem the electron mass has to be substituted by the reduced mass m∕2), as we presented in Sect. 2.3, and it is explicitly explained in [8].
