Quantum Statistical Mechanics: Selected Works Of N N Bogolubov: Selected Works of N N Bogolubov

In this book we have solved the complicated problem of constructing upper bounds for many-time averages for the case of a fairly broad class of model systems with four-fermion interaction. The methods proposed in this book for solving this problem will undoubtedly find application not only for the model systems associated with the theory of superconductivity considered here. The theoretical methods developed in Chapters 1 and 2 are already applicable to a much broader class of model systems from statistical physics and the theory of elementary particles.

Contents:

• On the Theory of Superfluidity
• Quasi-Averages in Problems of Statistical Mechanics
• Hydrodynamics Equations in Statistical Mechanics
• On the Hydrodynamics of a Superfluid Liquid
• On the Model Hamiltonian of Superconductivity
• Model Hamiltonians with Fermion Interaction

Readership: For research scientists and graduate students working in the field of quantum statistical mechanics.
Key Features:

• The book contains an exposition of very effective and powerful approach for practical applications techniques in quantum statistical mechanics
• All backgrounds, main mathematical approaches, techniques and derivations are presented in much detail that makes it possible to recommend the book as a manual for young researchers
• The derivations are, in some sense, unique to both the problems studied and methods devised for their solutions
