Theory of LMT atom interferometers involving gravitational fields (A05)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 274200144

Large momentum transfer (LMT) atom interferometers offer unprecedented perspectives for exploring the coupling of quantum matter to the gravitational field. A05 develops ab initio theory for the coupling of composite quantum systems, such as atoms, to gravity and the comprehensive theory of LMT atomic interferometers for experimental tests of this coupling. In close collaboration with the experimental projects B07 and B09, we will investigate new methodologies for the quantum control of cold atoms for matter wave interferometery. A05 thus contributes to the central vision of DQ-mat to test our understanding of basic physics at an unparalleled level with the targeted design of quantum states.
