Effects of relative phase and interactions on atom-laser outcoupling from a double-well Bose-Einstein condensate: Markovian and non-Markovian dynamics

TL;DR

This paper explores how the relative phase and interactions influence atom-laser outcoupling from a double-well Bose-Einstein condensate, analyzing both Markovian and non-Markovian dynamics using a mean-field two-mode model.

Contribution

It provides a theoretical analysis of atom-laser outcoupling dynamics considering phase and interaction effects in both Markovian and non-Markovian regimes.

Findings

Relative phase affects outcoupling efficiency.

Interactions modify the population dynamics.

Markovian and non-Markovian regimes exhibit distinct behaviors.

Abstract

We investigate aspects of the dynamics of a continuous atom-laser scheme based on the merging of independently formed atomic condensates. Our theoretical analysis covers the Markovian as well as the non-Markovian operational regimes, and is based on a semiclassical (mean-field) two-mode model. The role of the relative phase between the two condensates and the effect of interatomic interactions on the evolution of the trapped populations and the distribution of outcoupled atoms are discussed.
