Description for The Flow Equation Approach To Many-parti
Hardback. The flow equation approach consists of a sequence of infinitesimal unitary transformations and is conceptually similar to renormalization and scaling methods. The equations provide a framework for analyzing Hamiltonian systems where conventional many-body techniques fail. This book addresses the flow equation approach to many-particle systems. Series: Springer Tracts in Modern Physics. Num Pages: 184 pages, biography. BIC Classification: PH. Category: (UU) Undergraduate. Dimension: 234 x 156 x 12. Weight in Grams: 980.

Its basic concept was conceived independently by Wegner [1] and by G lazek and Wilson [2, 3]: the derivation of a unitary ?ow that makes a many-particle Hamiltonian - creasingly energy-diagonal. This concept can be seen as a generalization of theconventionalscalingapproachesinmany-bodyphysics,wheresomeult- violet energy scale is lowered down to the experimentally relevant low-energy scale [4]. The main di?erence between the conventional scaling approach and the ?ow equation approach can then be traced back to the fact that the ?ow equation approach retains all degrees of freedom, i. e. the full Hilbert space, while ...

Reviews for The Flow Equation Approach To Many-parti
From the reviews: “The book exposes the flow equation approach to many-particle systems … . The book is well written, in a pedagogical manner. It works out in detail exactly solvable models, like the potential scattering and the resonant level models, to develop the ideas and concepts, and then proceeds to their application to those nontrivial problems, making comparisons ...
