Statistical Approach to Quantum Field Theory
Springer International Publishing (Verlag)
978-3-030-83262-9 (ISBN)
This new expanded second edition has been totally revised and corrected. The reader finds two complete new chapters. One covers the exact solution of the finite temperature Schwinger model with periodic boundary conditions. This simple model supports instanton solutions - similarly as QCD - and allows for a detailed discussion of topological sectors in gauge theories, the anomaly-induced breaking of chiral symmetry and the intriguing role of fermionic zero modes. The other new chapter is devoted to interacting fermions at finite fermion density and finite temperature. Such low-dimensional models are used to describe long-energy properties of Dirac-type materials in condensed matter physics. The large-N solutions of the Gross-Neveu, Nambu-Jona-Lasinio and Thirring models are presented in great detail, where N denotes the number of fermion flavors. Towards the end of the book corrections to the large-N solution and simulation results of a finite number of fermion flavors are presented. Further problems are added at the end of each chapter in order to guide the reader to a deeper understanding of the presented topics. This book is meant for advanced students and young researchers who want to acquire the necessary tools and experience to produce research results in the statistical approach to Quantum Field Theory.
lt;p>Andreas Wipf is full professor at the Friedrich-Schiller-University (FSU) of Jena, Germany, where he teaches many courses related to theoretical physics. His research focuses on quantum field theory in the continuum and on lattice, structural aspects of quantum theory, quantum systems under extreme conditions, conformal and supersymmetric field theories, and the role of symmetries and symmetry breaking in theoretical physics. He obtained his Diploma at the Department of Physics at ETH Zurich, and his Ph.D. at the Institute for Theoretical Physics of the University of Zurich. He covered positions as postdoctoral fellow, assistant professor, and Privatdozent at the Dublin Institute for Advanced Studies, Los Alamos National Laboratory, Max-Planck-Institute for Physics (Werner-Heisenberg-Institute) in Munich, and at ETH Zurich where he habilitated in 1995. Then, he moved to Jena as full professor and has been Director of the Institute for Theoretical Physics, Dean of the Physics and Astronomy Faculty, Spokesman of the research training group on gravity, quantum field theory, and mathematical physics. He co-authored the textbooks "Theoretische Physik" (Springer Spektrum, 2015), which presents all theoretical physics up to the bachelor's degree and beyond, and "Theoretische Physik 3 Quantenmechanik" (Springer Spektrum, 2018).
