19. Okt. 2022 · A matter-wave interferometer is demonstrated with an interferometric phase noise below the standard quantum limit, combining two core concepts of quantum mechanics, that a particle can ...
Atominterferometer. 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.

For a free travelling matter waves, exponential, one can superimpose different wavevectors of the same modulus -- this is what one has in matter wave elastic diffraction. One can consider the small probe formed in scanning systems as an emergent phenomenon, as it comes from combining many waves. For a matter waves in a box you have to use cos/sin terms, you cannot separate the exponentials ...
De Broglie’s relations are usually expressed in terms of the wave vector →k , k = 2π / λ, and the wave frequency ω = 2πf, as we usually do for waves: E = ℏω →p = ℏ→k. Wave theory tells us that a wave carries its energy with the group velocity. For matter waves, this group velocity is the velocity u of the particle.
While the time-evolution process represented by the Schrödinger equation is continuous and deterministic, in that knowing the wave function at one instant is in principle sufficient to calculate it for all future times, wave functions can also change discontinuously and stochastically during a measurement. The wave function changes, according to this school of thought, because new information ...
Gravitational waves are waves of the intensity of gravity that are generated by the accelerated masses of binary stars and other motions of gravitating masses, and propagate as waves outward from their source at the speed of light. They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the ...
