Findings

Particle interactions significantly influence trap stability.

Stable and unstable regimes are mapped for different interaction types.

Variational techniques effectively determine phase-diagrams.

Abstract

We examine the properties of a quantum reflection trap when particle-interaction is included. We explore the influence of the particle-interaction on the trapping for different regimes: repulsive particle-interaction and attractive particle-interaction in its stable and unstable limit. With variational techniques, we calculate the phase-diagram of the quatum reflection trap and determine the stable and unstable regimes of the system.
