THE RENORMALIZATION GROUP AND CRITICAL PHENOMENA

Webb31 aug. 2024 · The renormalization of the band gap at finite temperatures is due to the lattice expansion and the phonon-induced atomic vibrations. In this work, we apply the recently-developed electron–phonon renormalization (EPR) method to study the temperature-dependent band gap in some classical covalent (diamond, Si, and SiC) and … Webb1 juli 1972 · A new regularization and renormalization procedure is presented. It is particularly well suited for the treatment of gauge theories. The method works for theories that were known to be renormalizable as well as for Yang-Mills type theories. Overlapping divergencies are disentangled. The procedure respects unitarity, causality and allows … the ages of the beatles band members https://dynamiccommunicationsolutions.com
