Influence of Nearly Resonant Light on the Scattering Length in Low-Temperature Atomic Gases.


We develop the idea of manipulating the scattering length a in low-temperature atomic gases by using nearly resonant light. As found, if the incident light is close to resonance with one of the bound p levels of electronically excited molecule, then virtual radiative transitions of a pair of interacting atoms to this level can significantly change the value… (More)
