Massless Lattice phi/sub 4//sup 4/ theory: A nonperturbative control of a renormalizable model
Journal Article
·
· Phys. Rev. Lett.; (United States)
We describe a rigorous argument establishing infrared asymptotic freedom and other related properties (e.g., scaling with logarithmic corrections) of the weakly coupled massless lattice phi/sup 4/ model in four Euclidean dimensions. Our method combines the block-spin renormalization-group analysis with the technique of convergent high-temperature expansions. It should also extend to the ultraviolet asymptotically free models such as the negative-coupling continuum phi/sub 4//sup 4/ theory.
