Near-field matter-wave optics:fundamentals and applications

Matter-wave interferometry can be applied for precision metrology with electrons, atoms and small molecules, in particular for the measurements of all kinds of inertial forces for instance the variations of the rotation of the Earth, local gravity acceleration (g) as well as gravity gradients. The knowledge of inertial forces is important for many fields and applications: geography, and geology, e.g. the gravity gradients can be caused from Earth quakes, geological deformations, waves (Tsunamis). In physics, the general relativity can be observed and better understood if one can search the gravitational waves, or even the fundamental constants, e.g. Newton’s constant, fine structure constant. The quantum mechanics of matter-wave interferometry can serve for the space applications, with space satellites, and eventually future space missions.In this research project, we will realize the first matter-wave interferometer in Thailand. The research project is relied on the strength of matter-wave interferometry that is sensitive to external perturbations or external fields which overcomes a light interferometry. We first perform our experiments with electrons and Rb cold atoms. In the talk, we will show how possible we will use our matter-wave interferometer for potential applications.
