Fluctuations and localization in mesoscopic electron systems

Tác giả: Lecture Notes, F. Strocchi

This book provides a readable account of the foundations of QFT, in particular of the Euclidean formulation with emphasis on the interplay between physical requirements and mathematical structures. The general structures underlying the conventional local (renormalizable) formulation of gauge QFT...

This is a selection of over 250 papers published by Abdus Salam, distinguished theoretical physicist and Nobel Prize winner for physics in 1979 for his work on the unification of electromagnetic and weak interactions. The papers represent a cross-section of his work over the past 50 years.

Non-Perturbative methods in 2 dimensional quantum field theory

Tác giả: Elcio Abdalla, M. Cristina B. Abdalla, Klaus D. Rothe

The second edition of "Non-Perturbative Methods in Two-Dimensional Quantum Field Theory" is an extensively revised version, involving major changes and additions. Although much of the material is special to two dimensions, the techniques used should prove helpful also in the development of...
