Abstract

We compute the shift of the transition temperature for a homogeneous weakly interacting Bose gas in leading order in the scattering length a for given particle density n. Using variational perturbation theory through six loops in a classical three-dimensional scalar field theory, we obtain DTc/Tc=1.25+-0.13an1/3, in agreement with recent Monte Carlo results.
