{"product_id":"hubbard-operators-in-the-theory-of-strongly-correlated-electrons","title":"Hubbard Operators In The Theory Of Strongly Correlated Electrons","description":"This book provides the first systematic discourse on a very peculiar approach to the theory of strongly correlated systems. Hubbard X-operators have been known for a long time but have not been widely used because of their awkward algebra. The book shows that it is possible to deal with X-operators even in the general multilevel local eigenstate system, and not just in the case of the nondegenerate Hubbard model. X-operators provide the natural language for describing quasiparticles in the Hubbard subbands with unusual doping and temperature-dependent band structures.The X-operator diagram technique is presented in detail, so that a newcomer with knowledge of the usual Fermi\/Bose operator diagram technique can use the former after reading the book.Examples are taken from the theory of high-Tc superconductivity, rare-earth compounds with strong magnetic anisotropy and quantum oscillations in strongly correlated systems.","brand":"Imperial College Press","offers":[{"title":"Default Title","offer_id":54236517237080,"sku":"9781860944307","price":107.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9781860944307.jpg?v=1777273266","url":"https:\/\/agendabookshop.com\/products\/hubbard-operators-in-the-theory-of-strongly-correlated-electrons","provider":"Agenda Bookshop","version":"1.0","type":"link"}
