Quantum reflection is a uniquely quantum phenomenon in which a compact object, such as a neutron or a small molecule, reflects smoothly and in a wavelike fashion from much larger surface, such as a pool of mercury. In contrast, a classically behaving neutron or molecule will strike the same surface much like a thrown ball, hitting only at one atomic-scale location where it is either absorbed or scattered. Quantum reflection provides a powerful experimental demonstration of particle-wave duality, since it is the extended quantum wave packet of the particle, rather than the particle itself, that reflects from the larger surface.

Property Value
dbo:abstract
  • Quantenreflexion ist ein Phänomen in der Quantenphysik, bei dem eine Materiewelle von einem anziehenden Potential reflektiert wird. Ein solches Phänomen ist in der klassischen Physik nicht möglich. Zum Beispiel würde man bei zwei sich anziehenden Magneten nicht erwarten, dass ein Magnet plötzlich (z. B. kurz vor deren Berührung) in die entgegengesetzte Richtung abgestoßen wird. (de)

  • 量子反射(Quantum reflection),是描述从引力势反射过来物质波的一种物理现象。在经典物理学中,这种现象是不可能出现的。比如说,当一个磁铁拉着另一个磁铁吸引靠近,并不会其中一个磁铁突然间反转并且对方推走。 (zh)
