On the one-hand, so-called single-particle methods are based on the study of a single electron moving in an effective field formed by the other electrons and the nuclei in the system. Band theory, as this approach is referred to, has had impressive successes in determining the equilibrium properties, such as structural stability, volume, and charge densities, of specific materials, notably metals. Today, even coherent phase diagrams (based on a single underlying lattice) for binary metallic alloys can be studied with considerable accuracy. In spite of its serious and well-understood limitations regarding the handling of correlations, band theory has been embraced by the materials scientist. Its single-particle nature endows the method with an economy of concepts which leads to a clear identification of mechanisms driving physical behavior at the electronic level. This perceived clarity often tends to override legitimate concerns regarding the validity of the method or its ability to correctly identify the | | 出版日期 | Book 1999 | | 关键词 | Metall; alloy; crystal; liquid; many-body theory; materials properties; metal | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4615-4715-0 | | isbn_softcover | 978-1-4613-7136-6 | | isbn_ebook | 978-1-4615-4715-0 | | copyright | Springer Science+Business Media New York 1999 |
