Output from an atom laser: theory vs. experiment

TL;DR

This paper compares theoretical predictions from coupled Gross-Pitaevskii equations with experimental data for atom laser outputs, demonstrating that the model accurately describes the rf-atom laser behavior.

Contribution

It introduces a detailed 1D GPE model for rf-atom lasers and validates it against recent experimental measurements for Rb-87.

Findings

The GPE model accurately predicts atom laser output.

Good agreement between theory and experiment for F=2 and F=1 states.

The model effectively describes the dynamics of rf-atom lasers.

Abstract

Atom lasers based on rf-outcoupling can be described by a set of coupled generalized Gross-Pitaevskii equations (GPE). We compare the theoretical predictions obtained by numerically integrating the time-dependent GPE of an effective one-dimensional model with recently measured experimental data for the F=2 and F=1 states of Rb-87. We conclude that the output of a rf-atom laser can be well described by this model.
