Degenerate approach to the mean field Bose- Hubbard Hamiltonian
A. M. Belemuk, V. N. Ryzhov
A degenerate variant of mean field perturbation theory for the on-site Bose-Hubbard Hamiltonian is presented. We split the perturbation into two terms and perform exact diagonaliza…

Effective Hamiltonian study of excitations in a boson- fermion mixture with attraction between components
A. M. Belemuk, V. N. Ryzhov
An effective Hamiltonian for the Bose subsystem in the mixture of ultracold atomic clouds of bosons and fermions with mutual attractive interaction is used for investigating collec…
