Electromagnetic theory balance

A simplified summary of electromagnetic interaction theory for chemists [7] shows that any interaction requires equal participation of an emitter and an absorber. The crucial argument is that emission without a receptive absorber and absorption in the absence of an emitter are equally unlikely events. What occurs in all cases is therefore best described as transmission. This means that emission, which causes propagation of energy as a function of time, is balanced by an inverse retrogression that runs from the absorber, backwards in time. If a signal, transmitted at time t0 from the emitter, triggers an... [Pg.183]

The Franck-Condon principle implies locality in phase space x, p. It states that the coordinate and momentum of a massive dot stay unchanged during the electron transitions, i.e. electron tunneling in our case. For detailed balance, the tunnel coupling Ta has to be invoked as the main prerequisite for the Coulomb blockade. The additional relaxation due to molecular collisions and electromagnetic radiation may have to be favored for the steady state. This is similar to the dissipation necessitated in the orthodox theory of the Coulomb blockade [Kulik 1975 Averin 1991],... [Pg.653]

Relativity theory has equally dramatic implications on the nature of the vacuum, which is shown not to be a void, but a medium that supports wave motion and carries electromagnetic fields. A new perspective on the nature of the vacuum is provided by the principle of equivalence. Space-time curvature can be described mathematically by a Riemann tensor, which the principle implies, should balance the gravitational field, which is sourced in the distribution of matter. This reciprocity indicates that Euclidean space-time is free of matter, which only emerges when curvature sets in. This is interpreted to mean that the homogeneous wave field of Euclidean vacuum generates matter when curved. Like a flat sheet that develops wrinkles when wrapped arormd a curved surface, the wave field generates non-dispersive persistent wave packets in the curved vacuum. [Pg.302]

Motion, stress, energy, entropy, and electromagnetism are the concepts upon which field theories are constructed. Laws of conservation or balance are laid down as relating these quantities in all cases. These basic principles, which are in integral form, in regions where the variables change sufficiently smoothly are equivalent to differential field equations at surfaces of discontinuity, to jump conditions. [Pg.278]
