... The last parenthesis is for emphasis. So, spinor solutions emerge from solutions in the algebra. Remark: Particles are spinors, but one still needs more structure before we can say “this spinor represents a particle”. On the other hand, specific particles have to do with specific idempotents and, t ...

... relativistic quantum mechanics which can be derived straightforwardly from classical special relativity, a well defined limit ofECE theory. It is shown in Section 2 that the Einstein energy equation can be quantized directly into a new type of linear, relativistic Schroedinger equation which reduces ...

... • To describe atoms with more than one electron, we also need to understand electron spin and the Pauli exclusion principle. These ideas explain why atoms that differ by just one electron (like lithium with three electrons per atom and helium with two electrons per atom) can be dramatically differen ...

Propagator

In quantum mechanics and quantum field theory, the propagator gives the probability amplitude for a particle to travel from one place to another in a given time, or to travel with a certain energy and momentum. In Feynman diagrams, which calculate the rate of collisions in quantum field theory, virtual particles contribute their propagator to the rate of the scattering event described by the diagram. They also can be viewed as the inverse of the wave operator appropriate to the particle, and are therefore often called Green's functions.
