The Bogoliubov-Bose-Hubbard model: existence of minimizers and absence of quantum phase transition

Norbert Mokrzański, Marcin Napiórkowski

We consider a variational approach to the Bose-Hubbard model based on Bogoliubov theory. We introduce the grand canonical and canonical free energy functionals for which we prove t…
