Matter waves are a central part of the theory of quantum mechanics, being half of wave–particle duality. At all scales where measurements have been practical, matter exhibits wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave.

Overview. Interferometry splits a wave into a superposition along two different paths. A spatially dependent potential or a local interaction differentiates the paths, introducing a phase difference between waves. Atom interferometers use center of mass matter waves with short de Broglie wavelength.
Ein Atominterferometer ist ein Interferometer, das die Welleneigenschaften von Atomen ausnutzt. Mit Atominterferometern lassen sich fundamentale Konstanten wie die Gravitationskonstante mit hoher Genauigkeit bestimmen, möglicherweise aber auch Phänomene wie Gravitationswellen untersuchen.
Matter waves of molecules as large as carbon \(C_{60}\) have been measured. All physical objects, small or large, have an associated matter wave as long as they remain in motion. The universal character of de Broglie matter waves is firmly established.
Sometimes in the field of physics "matter" is simply equated with particles that exhibit rest mass (i.e., that cannot travel at the speed of light), such as quarks and leptons. However, in both physics and chemistry, matter exhibits both wave -like and particle -like properties, the so-called wave–particle duality.
17. Okt. 2018 · Exploring the Universe with matter waves. An exotic ultracold gas known as a Bose–Einstein condensate has been produced and studied in space. Such gases could be used to build quantum sensors...
