Описание: This monograph deals with the quantum kinetics for transport in low-dimensional microstructures and for ultrashort laser pulse spectroscopy. The nonequilibrium Green function theory is described and used for the derivation of the quantum kinetic equations. Numerical methods for the solution of the retarded quantum kinetic equations are discussed and results are presented for quantum high-field transport and for mesoscopic transport phenomena. Quantum beats, polarization decay and non-Markovian behaviour are treated for femtosecond spectroscopy on a microscopic basis.

Эта монография посвящена квантовой кинетике в области транспорта и оптики полупроводников. Описывается уравнение Больцмана и численные методы его решения, основные квантовые кинетические уравнения, квантовые функции распределения, физика лазерного излучения и многое другое.

Из предисловия:
New textbooks on various aspects of theoretical physics seem to overflow the market. A prospective author must be able to provide convincing answers to at least the following questions (posed by the publisher, colleagues, and last but not least, by him/herself and the associated family members), (i) Why bother writing the book? (ii) Is there a sufficient audience for the text? (iii) Isn't the topic already covered by a number of books, and isn't the author's best hope just to add a new wrinkle to the existing lore (and perhaps enhance his/her own publication record)? (iv) Is there any practical need for the book? (v) Are there any important open problems that the book will contribute to finding solutions to (or, at least, be able to identify points where the present understanding is insufficient).
We have thought carefully about the above questions, and have become convinced (at least between ourselves), that indeed there is a purpose in writing the book that you are holding in your hands.
In what follows we will try to outline reasons why we feel that this book might be useful, and define its scope and ultimate goals. First of all. this is a book on a technique. More precisely, this is a book on nonequilibrium Green functions (NGF). Narrowing the definition down even more precisely, this is a book about how NGF are applied in semiconductor science. To identify the final qualifier, we are mostly interested in systems where extremely short length scales and extremely fast time scales (~ 1 fs) play a crucial role. In these short length and time scales the electrons exhibit their quantum mechanical wave nature: the quantum coherence of the electronic excitations becomes important. To properly describe phenomena of this kind, one needs a quantum theory of nonequilibrium phenomena, and the NGF provide such a technique. One of the purposes of this book is to show how deeply the quantum coherence modifies the physics in short time and length scales: the relaxation and dephasing dynamics differ radically from their semiclassical counterparts, and the collision terms of the quantum kinetic equations have a non-Markovian memory structure.
