Transition dipole moment — The Transition dipole moment or Transition moment, usually denoted scriptstyle{mathbf{d} {nm for a transition between an initial state, scriptstyle{m}, and a final state, scriptstyle{n}, is the electric dipole moment associated with the… … Wikipedia
Magnetic dipole transition — The interaction of an electromagnetic wave with an electron bound in an atom or molecule can be described by time dependent perturbation theory. Magnetic dipole transitions describe the dominant effect of the coupling to the magnetic part of the… … Wikipedia
Vacuum Rabi oscillation — A vacuum Rabi oscillation is a damped oscillation of an initially excited atom coupled to an electromagnetic resonator or cavity in which the atom alternately emits photon(s) into a single mode electromagnetic cavity and reabsorbs them. The atom… … Wikipedia
radioactivity — /ray dee oh ak tiv i tee/, n. Physics, Chem. the phenomenon, exhibited by and being a property of certain elements, of spontaneously emitting radiation resulting from changes in the nuclei of atoms of the element. Also called activity. [1895… … Universalium
Van Hove singularity — A Van Hove singularity is a kink in the density of states (DOS) of a solid. The wavevectors at which Van Hove singularities occur are often referred to as critical points of the Brillouin zone. (The critical point found in phase diagrams is a… … Wikipedia
QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… … Wikipedia
Bhabha scattering — Notice that there is a relative sign difference between the two diagrams.quare of matrix elementTo calculate the unpolarized cross section, one must average over the spins of the incoming particles ( s e and s e+ possible values) and sum over the … Wikipedia
Orbital magnetization — Orbital magnetization, , refers to the magnetization induced by orbital motion of charged particles, usually electrons, in solids. The term orbital distinguishes it from the contribution of spin degrees of freedom, , to the total magnetization. A … Wikipedia
Computational electromagnetics — Computational electromagnetics, computational electrodynamics or electromagnetic modeling is the process of modeling the interaction of electromagnetic fields with physical objects and the environment. It typically involves using computationally… … Wikipedia
