{"product_id":"9781860944307","title":"Hubbard Operators in the Theory of Strongly Correlated Electrons","description":"\u003cp\u003eThis 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.\u003c\/p\u003e","brand":"Imperial College Press","offers":[{"title":"Default Title","offer_id":47038925013232,"sku":"9781860944307","price":114.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781860944307_p0.jpg?v=1763600339","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781860944307","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
