A strong coupling expansion, based on the Kato-Bloch perturbation theory,which has recently been proposed by Eckardt et al. [Phys. Rev. B 79, 195131]and Teichmann et al. [Phys. Rev. B 79, 224515] is implemented in order to studyvarious aspects of the Bose-Hubbard and the Jaynes-Cummings lattice model. Theapproach, which allows to generate numerically all diagrams up to a desiredorder in the interaction strength is generalized for disordered systems and forthe Jaynes-Cummings lattice model. Results for the Bose-Hubbard and theJaynes-Cummings lattice model will be presented and compared with results fromVCA and DMRG. Our focus will be on the Mott insulator to superfluid transition.
