AcknowledgementsThe research included in this dissertation could not have been performed if not for the assistance, patience, and support of many individuals. I would like to extend my gratitude first and foremost to my thesis advisor Dr. Elcio Abdalla for mentoring me over the course of my graduate studies. He has helped me through extremely difficult times over the course of the analysis and the writing of the dissertation and for that I sincerely thank him for his confidence in me.
A many‐body theoretical scheme based on the functional Schrödinger picture method is formulated for the study of a dilute Bose gas system. The standard ground state properties are obtained by solving the infinite dimensional Schr�dinger equation variationally with a Gaussian trial wavefunctional. It is shown that a shifted Gaussian trial functional enables us to calculate a higher order correction of order na3, which corresponds to the fluctuation constribution from the condensate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
