One-dimensional Bose-Hubbard model with local three-body interactions
S. Ejima, F. Lange, H. Fehske +2
We employ the (dynamical) density matrix renormalization group technique to investigate the ground-state properties of the Bose-Hubbard model with nearest-neighbor transfer amplitu…

Characterization of Mott-insulating and superfluid phases in the one-dimensional Bose--Hubbard model
Satoshi Ejima, Holger Fehske, Florian Gebhard +4
We use strong-coupling perturbation theory, the variational cluster approach (VCA), and the dynamical density-matrix renormalization group (DDMRG) method to investigate static and…
