Feynman Diagrams for Beginners
... We give a short introduction to Feynman diagrams, with many exercises. Text is targeted at students who had little or no prior exposure to quantum field theory. We present condensed description of single-particle Dirac equation, free quantum fields and construction of Feynman amplitude using Feynman ...

In the method proposed here there is no need to introduce idealized quasi-particles, and the experimental results can be interpreted in terms of a simple assumption connected with the self-consistent field. To this aim, let us observe that the Lennard-Jones intermolecular potential model describes i ...

By constrained motion, we mean motion in which external constraints act to keep the particle on a predetermined trajectory. The effect of the constraint force is to assure th ...
