Title: One dimensional Bose-Einstein condensate under the effect of the extended uncertainty principle
(Submitted on 21 Jul 2023 (v1), revised 26 Jul 2023 (this version, v2), latest version 8 Apr 2024 (v4))
Abstract: In this study, an analytical investigation was conducted to assess the effects of the extended uncertainty principle (EUP) on a Bose-Einstein condensate (BEC) described by the deformed one-dimensional Gross-Pitaevskii equation. Analytical and variational solutions were derived for both null and harmonic potentials. Subsequently, we analyzed the probability density and the uncertainty of the position as functions of the deformation parameter $\alpha$. Our findings reveal that the EUP significantly impacts the amplitude and uncertainty position of the bright and dark soliton solutions.
