  • Two-photon absorption — (TPA) is the simultaneous absorption of two photons of identical or different frequencies in order to excite a molecule from one state (usually the ground state) to a higher energy electronic state. The energy difference between the involved… …   Wikipedia

  • Two-photon physics — Two photon physics, also called gamma gamma physics, is a branch of particle physics for the interactions between two photons. If the energy in the center of mass system of the two photons is large enough, matter can be created.Fact|date=May… …   Wikipedia

  • Photon gas — In physics, a photon gas is a gas like collection of photons, which has many of the same properties of a conventional gas like hydrogen or neon including pressure, temperature, and entropy. The most common example of a photon gas in equilibrium… …   Wikipedia

  • Monte Carlo method for photon transport — Modeling photon propagation with Monte Carlo methods is a flexible yet rigorous approach to simulate photon transport. In the method, local rules of photon transport are expressed as probability distributions which describe the step size of… …   Wikipedia

  • Drell–Yan process — Drell–Yan process: a quark from one hadron and an antiquark from another hadron annihilate to create a pair of leptons through the exchange of a virtual photon. The Drell–Yan process occurs in high energy hadron–hadron scattering. It takes place… …   Wikipedia

  • Drell-Yan process — The Drell Yan process occurs in high energy nucleon nucleon scattering. It takes place when a quark of one hadron and an antiquark of another (anti )hadron annihilate and create a pair of oppositely charged leptons. The production of such lepton… …   Wikipedia
