The approach, quite traditionally, uses the mathematical formalism of quasiparticles and Green‘s functions. In particular, it covers all the important diagram techniques for normal and superconducting systems, including the zero- temperature perturbation theory, and the Matsubara, Keldysh, and Nambu -Gor‘kov formalisms. The aim is not to be exhaustive, but to present just enough detail to enable the student to follow the current research literature or to apply the techniques to new problems. Many of the examples are drawn from mesoscopic physics, which deals with systems small enough that quantum coherence is maintained throughout their volume, and which therefore provides an ideal testing ground for many-body theories. The book begins by introducing the Green‘s function for one-particle systems (using Feynman path integrals), general perturbation theory, and second quantization. It then turns to the usual zero-temperature formalism, discussing the properties and physical meaning of the Green‘s function | | 出版日期 | Textbook 19981st edition | | 關鍵詞 | Second quantization; coherence; condensed matter; electron; many-body theory; path integral; perturbation | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4612-0595-1 | | isbn_softcover | 978-1-4612-6831-4 | | isbn_ebook | 978-1-4612-0595-1Series ISSN 0938-037X | | issn_series | 0938-037X | | copyright | Springer Science+Business Media New York 1998 |
