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.
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.
An atom interferometer is an interferometer which uses the wave character of atoms. Similar to optical interferometers, atom interferometers measure the difference in phase between atomic matter waves along different paths. Today, atomic interference is typically controlled with laser beams.
Compton’s formula established that an electromagnetic wave can behave like a particle of light when interacting with matter. In 1924, Louis de Broglie proposed a new speculative hypothesis that electrons and other particles of matter can behave like waves. Today, this idea is known as de Broglie’s hypothesis of matter waves.
In quantum mechanics, a branch of physics, a matter wave is when you think of matter as a wave. The concept of matter waves was first introduced by Louis de Broglie. Matter waves are hard to visualize, because we are used to thinking of matter as a physical object.
17. Okt. 2018 · A fundamental principle of quantum physics is wave–particle duality, which describes elementary particles in terms of quantum-mechanical waves (de Broglie waves). The higher the velocity of a...
It turns out that electrons have wave-like properties and also undergo Bragg diffraction by crystals. Bragg diffraction thus provides a crucial bridge between the worlds of waves and particles. With this bridge we introduce the classical ideas of momentum and energy by relating them to the wave vector and frequency of a wave. The properties of ...
