The Principle of Equivalence lies at the heart of the theory of General Relativity. Taking the advantage of long free evolution times, mass independent confining potentials and perturbation free environment, QUANTUS2 aims to push the existing frontiers further to perform high precision experiments in the quantum domain. In this context, we realize a new setup fulfilling the criteria of being extremely compact, in order to operate in the catapult mode of the droptower in Bremen doubling the time of microgravity up to 9 seconds. The experiment is planned to use 87Rb and 40K as degenerate Bose-Fermi mixtures in order to carry out experiments on tests of the Weak Equivalence Principle in quantum domain. Up to date progress and future prospects of this ambitious and technically challenging project will be presented in this talk.
The QUANTUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0835-0839.
