Wave-packet analysis of interference patterns in output coupled atoms
arXiv:1002.4184 · doi:10.1103/PhysRevA.81.043638
Abstract
We study the output coupling of atoms from a magnetic trap into a linear potential slope of gravity using a weak radio-frequency field. We present a one-dimensional wave-packet model based on a continuous loading of a continuous spectrum of generalised eigenstates to describe the scenario. Analyzing the model, we show how the interference of the classical coupling fields maps to the interference of the resulting atomic streams.
