Measurements of the Geometric Phase of First-Order Optical Gaussian Beams
... Geometric phase is ubiquitous in systems that undergo cyclic transformations in either parameter or state space. Manifestations of this phase have been found in many physical systems. In optics, geometric phase has had an important effect, enhancing the way optical systems are analyzed, and stimulat ...

Electrons in Atoms
... Proposed that one cannot predict exactly where a particle will move since it’s impossible to measure the location and momentum of a particle simultaneously. Leads to the proposition that electron position around a nucleus cannot be precisely known, only predicted with a given probability. Erwi ...

Quantum spin
... Historically, Bethe's 1931 work on the isotropic case (gx = gy = gz), known as the XXX model, had a major impact and was the starting point for many of the subsequent developments in this area. He made an "ansatz" for the stationary states of the XXX spin-chain to be a superposition of plane waves ( ...

Brief history of the atom
... Next, Millikan applied a charge to the falling drops by irradiating the bottom chamber with x-rays. This caused the air to become ionized, which basically means that the air particles lost electrons. A part of the oil droplets captured one or more of those extra electrons and became negatively charg ...
