Anomalous quantum-reflection of Bose-Einstein condensates as a self-screening effect

TL;DR

This paper investigates how Bose-Einstein condensates exhibit anomalous quantum reflection due to a self-created screening effect, using a new theoretical approach and comparing it with experimental data.

Contribution

It introduces a novel single-mode theoretical framework to analyze anomalous quantum reflection in Bose-Einstein condensates, highlighting the self-screening mechanism.

Findings

The theory matches experimental observations.

Self-screening significantly influences quantum reflection.

Different reflection paths are characterized by the model.

Abstract

We discuss the effect of anomalous quantum-reflection of Bose-Einstein condensates as a screening effect, that is created by the condensate itself. We derive an effective, time-independent single-mode approach, that allows us to define different paths of reflection. We compare our theory with experimental results.
