One of the most original predictions of general relativity is the coupling between gravity and any physical entity described by a stress–energy tensor. In this picture, even quantum fields should warp space–time and be affected by its curvature. Nonetheless, the interaction between quantum fields and gravity is still debated and the gravitational interaction of the quantum vacuum energy has not yet been observed. Archimedes is an experiment designed to measure the weight of the vacuum, i.e., the coupling of vacuum energy with gravity. Using a specifically designed high-precision cryogenic balance, we will measure the weight of a multi-layered superconductive crystal. In such a system, the Casimir energy of the electromagnetic vacuum can be modulated, triggering the superconductive phase transition.View this paper.
