... To regulate the infra-red divergences, we’ll make the x1 direction periodic, with size L, and impose periodic boundary conditions such that φ(~x) = φ(~x + L~n) with ~n = (1, 0, 0). We’ll leave y and z alone, but remember that we should compute all physical quantities per unit area A. We insert two r ...
