Photons

Some articles on photons:

Soft Photons
... In particle physics, soft photons are photons with energies much smaller than the energies of the particles participating in a particular scattering process, and they are not energetic enough to be ... Such photons can be emitted from (or absorbed by) the external (incoming and outgoing) lines of charged particles of the Feynman diagram for the process ... Even though soft photons are not detected, the possibility of their emission must be taken into account in the calculation of the scattering amplitude ...
Transparent Materials
... the dimensions investigated are much, much larger than the wavelength of the photons in question), the photons can be said to follow Snell's Law ... the macroscopic scale) follow Snell's law the photons can be scattered at either of the two interfaces where there is a change in index of refraction, or internally ... Photons interact with an object by some combination of reflection, absorption and transmission ...
CENBOL - Centrifugal Force
... it is hot, it inverse Comptonizes soft photons or seed photons and produces very high energy hard photons ... effects, CENBOL may start to oscillate and then the number of intercepted soft photons would be modulated ... As a result, the number of hard photons are also modulated producing what is known as quasi-periodic oscillations (or QPOs) ...
Chameleon Particle - Hypothetical Properties
... Chameleons also couple to photons, allowing photons and chameleons to oscillate between each other in the presence of an external magnetic field ... One strategy to search experimentally for chameleons is to direct photons into a cavity, confining the chameleons produced, and then to switch off the light source ... Chameleons would be indicated by the presence of an afterglow as they decay back into photons ...
Cavity Quantum Electrodynamics
... conditions where the quantum nature of light photons is significant ... that is between an excited atom and n-1 photons, and a ground state atom and n photons ... the atomic transition, a half-cycle of oscillation starting with no photons coherently swaps the atom qubit's state onto the cavity field's, and can be repeated to swap it back again this could be used as ...
