Signatures of Strong Momentum Localization via Translational-Internal Entanglement
arXiv:cond-mat/0609282 · doi:10.1103/PhysRevLett.97.230402
Abstract
We show that atoms or molecules subject to fields that couple their internal and translational (momentum) states may undergo a crossover from randomization (diffusion) to strong localization (sharpening) of their momentum distribution. The predicted crossover should be manifest by a drastic change of the interference pattern as a function of the coupling fields.
