Abstract
By resonantly associating laser-cooled atoms, it is now possible to produce diatomic molecules referred to as Fano-Feshbach molecules. The absolute ground state of a polar molecule having been achieved with the Fano-Feshbach molecule as a seed, the coldmolecule production, owing to its groundbreaking opportinities, is attracting much attention. However, the molecular production takes place amongst many ultracold atoms, thus necessitating the examination of the many-particle effect. We present how the behavior based on the famous two-state Landau-Zener formula for the "atom+atom" and "diatom" states gets modified due to the nonlinear dynamics of many atoms which tends to soften the adiabaticity.
