Two-photon physics, also called gamma–gamma physics, is a branch of particle physics that describes the interactions between two photons. Normally, beams of light pass through each other unperturbed. Inside an optical material, and if the intensity of the beams is high enough, the beams may affect each … See more Cosmological/intergalactic gamma rays Photon–photon interactions limit the spectrum of observed gamma-ray photons at moderate cosmological distances to a photon energy below around 20 GeV, that is, to a See more Two-photon physics can be studied with high-energy particle accelerators, where the accelerated particles are not the photons themselves but charged particles that will radiate photons. The most significant studies so far were performed at the See more • Channelling radiation has been considered as a method to generate polarized high energy photon beams for gamma–gamma colliders. • Matter creation • Pair production See more From quantum electrodynamics it can be found that photons cannot couple directly to each other and a fermionic field according to the Landau-Yang theorem since they carry no charge and no 2 fermion + 2 boson vertex exists due to requirements of … See more • Lauber,J A, 1997, A small tutorial in gamma–gamma Physics • Two-photon physics at LEP • Two-photon physics at CESR See more opticians moffat scotland

Our device is based on a single atom coupled to a fiber-coupled, chip-based microresonator. A single reflected control photon toggles the switch from high reflection ( R ~ 65%) to high transmission ( T ~ 90%), with an ...
