Bosonization of Interacting Fermions in Arbitrary Dimensions

Publisher: arXiv 2006
Number of pages: 287
In this book we describe a new non-perturbative approach to the fermionic many-body problem, which can be considered as a generalization to arbitrary dimensions of the well-known bosonization technique for one-dimensional fermions. Our approach is based on the direct calculation of correlation functions of interacting Fermi systems with dominant forward scattering via functional integration and Hubbard-Stratonovich transformations.

This introductory text was aimed at giving a basic knowledge of the concepts and methods of statistical physics to the readers, so that they could later on follow more advanced lectures on diverse topics in the field of complex systems.

A new approach towards the foundations of Statistical Mechanics is explored. The approach is genuine quantum in the sense that statistical behavior is a consequence of objective quantum uncertainties due to entanglement and uncertainty relations.
