TL;DR
This paper develops a theoretical framework for Bose-Einstein condensates using su(1,1) algebra, providing a detailed description of the ground state and excited states, and compares the model with experimental correlation data.
Contribution
It introduces a novel su(1,1) algebraic approach to modeling the BEC ground state and weakly excited states, enhancing understanding of condensate structure.
Findings
The constructed wave function accurately predicts second and third order correlation functions.
The su(1,1) structure offers a new perspective on BEC ground state properties.
Comparison with experiments validates the theoretical model.
Abstract
We construct a macroscopic wave function that describes the Bose-Einstein condensate and weakly excited states, using the su(1,1) structure of the mean-field hamiltonian, and compare this state with the experimental values of second and third order correlation functions.
