Squeezed atom laser for Bose-Einstein condensate with minimal length

TL;DR

This paper proposes a method to generate a squeezed atom laser from a Bose-Einstein condensate using a model based on the generalized uncertainty principle, where squeezing arises naturally from the system's structure without external squeezed light.

Contribution

It introduces a novel approach to produce squeezed atom lasers leveraging noncommutative geometry effects, eliminating the need for external squeezed light sources.

Findings

Squeezing occurs automatically due to the model's structure.

Analytical and numerical analysis confirms squeezing effects.

The method enhances atom laser coherence without external squeezing.

Abstract

We study a protocol for constructing a squeezed atom laser for a model originating from the generalized uncertainty principle. We show that the squeezing effects arising from such systems do not require any squeezed light as an input, but the squeezing appears automatically because of the structure of the model it owns. The output atom laser beam becomes squeezed due to the nonlinear interaction between the Bose-Einstein condensate and the deformed radiation field created due to the noncommutative structure. We analyze several standard squeezing techniques based on the analytical expressions followed by a numerical analysis for further insights.
