Dyson formula
WebDyson’s expansion is widely used in quantum electrodynamics. If one uses a classical field to describe an external field imposed upon the system, then the potential V has its own explicit time dependence. In this case, the hamiltonian Hinherits the … http://quantum.phys.unm.edu/521-07/interactionPicture.pdf

WebMar 6, 2024 · Hi everyone, In his book "Quantum field theory and the standard model", Schwartz derives the position-space Feynman rules starting from the Schwinger-Dyson formula (section 7.1.1). I have two questions about his derivation. 1) As a first step, he rewrites the correlation function as. where is the Feynman propagator, such that.

In 1956, F.Spitzer fully described the maximum of a random walk with the help of a remarkable combinatorial theorem of H.F.Bohnenblust.
