Exact diagonalization of the one dimensional Bose-Hubbard model with
local 3-body interactions    [PDF]

Tomasz Sowinski

In this article the extended Bose-Hubbard model with local two- and three-
body interactions is studied by exact diagonalization approach. Shapes of the
first two insulating lobes are discussed and values of the critical tunneling
for which the insulating phase loses stability for different three-body
interactions are predicted.
