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":"Hardcover","offer_id":47892168442007,"sku":"9781860944307","price":13565.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781860944307.webp?v=1781185954","url":"https:\/\/atlanticbooks.com\/products\/hubbard-operators-in-the-theory-of-strongly-correlated-electrons-9781860944307","provider":"Atlantic Books","version":"1.0","type":"link"}
