Optical tuning of the scattering length in a Bose-Einstein condensate as predicted by Fedichev et al is demonstrated. Atoms in a /sup 87/rubidium condensate were exposed to laser light tuned close to the transition frequency to a molecular state. The optical coupling of the atomic scattering state to the molecular state gives rise to what is called an ...

Optical Feshbach Resonance Using the Intercombination Transition
Physical Review Letters, 2008We report control of the scattering wave function by an optical Feshbach resonance effect using ytterbium atoms. The narrow intercombination line (1S0-3P1) is used for efficient control as proposed by Ciuryło et al. [Phys. Rev. A 71, 030701(R) (2005)10.1103/PhysRevA.71.030701].

Feshbach Resonances in Chemical Reactions
1981Publisher Summary This chapter reviews Feshbach theory and discusses applications that are developed to observe chemical reactions. The time-independent formulation was then applied to a model four-channel reaction involving two open channels interacting with two asymptotically closed channels.

Corrections to Feshbach resonance calculations
Physical Review A, 1977The Feshbach optical-potential formalism yields resonance parameters which may differ slightly from those usually defined. By employing the definition of resonances in terms of poles of the analytically continued S matrix, corrections are derived which reconcile the two sets of parameters.

Generalized saddle-point method for Feshbach resonances
Physical Review A, 1989The mini-max principle is extended to work for the approximations to resonances in the square-integrable function space. The hole-projection (or saddle-point) technique for Feshbach resonances, introduced previously by Chung [Phys. Rev. A 20, 1743 (1979)], is derived from the mini-max principle.
