Strong-coupling phi(4)-theory in 4-epsilon dimensions, and critical exponents

摘要

With the help of variational perturbation theory we continue the renormalization constants of phi(4)-theories in 4-epsilon dimensions to infinitely strong bare couplings g(0) and find their power behavior in g(0), thereby determining all critical exponents without the standard renormalization group techniques.
