Non-Markovian dynamics in atom-laser outcoupling from a double-well Bose-Einstein condensate

TL;DR

This paper explores the non-Markovian dynamics of atom-laser outcoupling from a double-well Bose-Einstein condensate, focusing on intermediate distances and mean-field behavior to understand population and energy distributions.

Contribution

It introduces a two-mode model for analyzing non-Markovian effects in atom-laser outcoupling from double-well condensates, a novel approach in this context.

Findings

Identification of quasi steady-state populations

Analysis of energy distribution of outcoupled atoms

Demonstration of non-Markovian effects in the dynamics

Abstract

We investigate the dynamics of a continuous atom laser based on the merging of independently formed atomic condensates. In a first attempt to understand the dynamics of the system, we consider two independent elongated Bose-Einstein condensates which approach each other and focus on intermediate inter-trap distances so that a two-mode model is well justified. In the framework of a mean-field theory, we discuss the quasi steady-state population of the traps as well as the energy distribution of the outcoupled atoms.
