Abstract: We apply the Bogoliubov inequality to the Bose–Hubbard model to rule out the possibility of Bose–Einstein condensation. The result holds in one and two dimensions for any filling at any nonzero temperature. This result can be considered as complementary to the analogous, classical result known for interacting bosons in a continuum.
