The applications of functional integral methods introduced in this text for solving a range of problems in quantum field theory will prove useful for students and researchers in theoretical physics and quantum field theory.On inspection, using the rules for diagrams given above, we see that N is the a#39; suma#39; of all vacuum to vacuum diagrams. ... To find a non-trivial application that is solvable we need to consider a two-field model with a Yukawa (i.e. tri-linear)anbsp;...
