Complex $\varphi^4$ Theory at Finite Temperature and Density via Extended Mean Field Theory

We review the Extended Mean Field (EMFT) approximation and apply it to complex, scalar $\varphi^4$ theory on the lattice. We determine the ($T,\mu$) phase diagram and study the critical properties of the Bose condensation transition, at zero and finite temperature. In both cases we obtain results wh...
