Bose-Fermi-Hubbard model on a lattice with two nonequivalent sublattices

Phase transitions in systems described by Bose-Fermi-Hubbard model on a lattice with two nonequivalent sublattices are investigated in this work. The case of hard-core bosons is considered and pseudospin formalism is used. Phase diagrams are built in the plain of chemical potential of the bosons-bos...

У цiй роботi дослiджено фазовi переходи у системах, що описуються моделлю Бозе-Фермi-Габбарда на ґратцi з двома нееквiвалентними пiдґратками. Розглянуто випадок жорстких бозонiв та використано псевдоспiновий формалiзм. Побудовано фазовi дiаграми у площинi хiмiчний потенцiал бозонiв-бозонний параметр перескоку. Показано, що у випадку анiзотропного перескоку область iснування так званої “суперсолiд” фази звужується. 2011 Article Bose-Fermi-Hubbard model on a lattice with two nonequivalent sublattices / T.S.
