Scientific Publishing Non-Perturbative Renormalization

The notion of renormalization is at the core of several spectacular achievements of contemporary physics, and in the last years powerful techniques have been developed allowing to put renormalization on a firm mathematical basis. This book provides a self-consistent and accessible introduction to the sophisticated tools used in the modern theory of non-perturbative renormalization, allowing an unified and rigorous treatment of Quantum Field Theory, Statistical Physics and Condensed Matter models. In particular the first part of this book is devoted to Constructive Quantum Field Theory, providing a mathematical construction of models at low dimensions and discussing the removal of the ultraviolet and infrared cut-off, the verification of the axioms and the validity of Ward Identities with the relative anomalies. The second part is devoted to lattice 2D Statistical Physics, analyzing in particular the theory of universality in perturbed Ising models and the computation of the non-universal critical indices in Vertex or Ashkin-Teller models. Finally the third part is devoted to the analysis of complex quantum fluids showing Luttinger of Fermi liquid behavior, like the 1D or 2D Hubbard model. Review The book is organized and edited in a cohesive manner to facilitate learning. It is recommendable for researchers in the renormalization group techniques and their applications for which it constitutes a compendium of the different modern approaches used to deal with current problems in the field. Some parts could be taken as a PhD course. Physicists and mathematicians can find an interesting and enlightening introduction to the modern theory of renormalization. --Journal of Statistical Physics
