Фермiонний спектр моделi Бозе–Фермi–Хаббарда у фазi з Бозе-конденсатом
We investigate the fermion spectrum within the Bose–Fermi–Hubbard model used for the description of boson-fermion mixtures of ultra-cold atoms in optical lattices. We used the method based on the Hubbard operator approach for an on-site basis. The equation for fermion Green’s function in the Bose–Fe...
