The Schrieffer-Wolff transformation, the Bogoliubov transformation, and the Green-function technique are applied as methods.In part II models for high-Tc superconductivity (HTSC) in cuprates are investigated. In 1986 HTSC for La2-x Bax CuO4 , with Tc = 30 K at x = 0.2, was demonstrated for the first time by Bednorz and Müller. Based on the experimental background up to 1992 the Emery model and the Anderson-lattice model play a fundamental role at the theoretical description. The system of itinerant O(p) holes and localized Cu(d) spins is used to deduce the so-called t-J or p-d models. Here the tpp - Jpd - Jdd model is derived. There appears a competition between antiferromagnetism and possible HTSC.\u003c\/div\u003e\u003ch4\u003eWeitere Angaben\u003c\/h4\u003e\u003cdiv\u003eBuch (Paperback), Englisch, 259 Seiten\u003c\/div\u003e","brand":"Weltbild.ch: Bücher \u0026 Outlet","offers":[{"title":"Default Title","offer_id":65914419151197,"sku":"K010803583","price":30.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0911\/8915\/0045\/files\/1080358300001A.jpg?v=1789357144","url":"https:\/\/weltbild.ch\/products\/microscopic-concepts-of-superconductivity-edeltraud-kolley","provider":"Weltbild.ch Bücher \u0026 Outlet","version":"1.0","type":"link"}
