Feshbach resonance pdf
WebJun 14, 2005 · We present a two-channel model to describe the quantum state of two atoms with finite-range interaction near a Feshbach resonance. This model provides a simple picture to analytically derive the wave function and the binding energy of the molecular bound state. The results agree excellently with the measurements and multichannel … WebApr 18, 2015 · In the simplest picture, the formula is. a ( B) = a 0 ( 1 − Δ B B − B r), where a 0 is the scattering length far from the resonance in question, Δ B is the so-called width of the resonance, and B r is the magnetic field strength at which the resonance happens. Note that the resonance happens when the energy of the two incoming atoms is ...
