Abstract

We study the critical region of the O(2)ϕ4O(2)\,\phi^4 theory by means of Monte Carlo simulations on the lattice. In particular we determine the ratio Δϕ2c/g\Delta\langle\phi^2\rangle_c/g in order to estimate the first correction to the critical temperature of a weak interacting Bose gas.
