In coordinates adapted to the outlined structure, using the Killing parameter as time, the metric takes a form different from Minkowski. Obviously the metric is flat, but it simulates a curved metric due to the presence of inerti ...

In chapter 3, we set up a natural framework for doing bound-state calculations within relativistic quantum theory. Fi ...

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.
