Investigating dark energy, which constitutes 70% of the universe’s energy and drives its accelerated expansion, remains a fundamental challenge. Scalar fields with screening mechanisms such as chameleon, symmetron and galileon have been proposed as potential explanations for dark energy. Cold atom experiments, particularly in chameleon and symmetron parameter constraints, have been valuable but face limitations due to the uncertainties on the gravity interactions between test masses and atoms.
This presentation discusses the collaborative D3E3/DESIRE project between JPL and Leibniz University Hannover. Utilizing atom interferometers in the microgravity environment of the Einstein-Elevator, the project aims to modify the scientific payload from the MAIUS-1 sounding rocket mission. This modification involves implementing a periodic test masse and multi-loop atom interferometers to enhance dark energy model constraints.
The DESIRE project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics Affairs and Climate Action (BMWK) under grant number 50WM2155
