The photoelectric ... In Einstein’s approach, a beam of monochromatic light of frequency \(f\) is made of photons. A photon is a particle of light. Each photon moves at the speed of light and carries an energy quantum \(E_f\). A photon’s energy depends only on its frequency \(f\). Explicitly, the energy of a photon is
WebPropagator. In quantum mechanics and quantum field theory, the propagator is a function that specifies the probability amplitude for a particle to travel from one place to another in a given period of time, or to travel with a certain energy and momentum.

WebSomething's very wrong with your differential equation for the Green's function D μ ν. Namely, the LHS is a scalar (-valued function), whereas the δ ν μ makes the RHS into a matrix (-valued function).
