We proved the spectrum of the system in the sextet state is purely continuous and in the system five-electron bound states and five-electron anti bound states is absent. In the one- and two-dimensional cases, it is shown that the essential spectrum of the five-electron quartet states operator is the union of seven segments, and the discrete spectrum of the system consists of a no more than one eigenvalue lying the outside domain of the essential spectrum of this operator.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786207462025\"\u003e\u003ch3\u003eOf the energy operator of five-electron system in the Hubbard model\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786207462025","offer_id":48473437143365,"sku":"9786207462025","price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/180951e1-c46f-4c62-8a83-019aca5e5987.jpg?v=1759213197","url":"https:\/\/shop.autorenwelt.de\/products\/structure-of-essential-spectrum-and-discrete-spectra-von-sa-dulla-tashpulatov","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
