Providing a systematic introduction to the techniques which are fundamental to quantum field theory, this book pays special attention to the use of these techniques in a wide variety of areas, including ordinary quantum mechanics, quantum mechanics in the second-quantized formulation, relativistic quantum field theory, Euclidean field theory, quantum statistics at finite temperature, and the classical statistics of nonideal gas and spin systems. The extended chapter on variational methods and functional Legendre transformations contains completely original material.

This long-standing, widely respected series was founded in 1961 in an effort to put forward coherent works that summarize developments in the most active and interesting areas of physics. It continues to serve that need, including textbooks, monographs, lecture notes, and professional manuals that aid in offering synthetic, authoritative accounts of the present state of the art in key subject areas of wide interest to physicists. The caliber of authors published in the series speaks to the high standards of its publication: R. P. Feynman, D. Pines, L. P. Kadanoff, R. Hofstadter, J. Schwinger, and many others.
New books in the series are commissioned by invitation. Authors are also welcome to contact the publisher, Lou Chosen, Executive Editor, email@example.com, to discuss new title ideas.
