Dynamic response of spin-2 bosons in one-dimensional optical lattices
Florian Lange, Satoshi Ejima, Holger Fehske
We investigate the spin-2 chain model corresponding to the small hopping limit of the spin-2 Bose-Hubbard model using density-matrix renormalization-group and time-evolution techni…
Quantum phase transitions in the dimerized extended Bose-Hubbard model
Koudai Sugimoto, Satoshi Ejima, Florian Lange +1
We present an unbiased numerical density-matrix renormalization group study of the one-dimensional Bose-Hubbard model supplemented by nearest-neighbor Coulomb interaction and bond…
Strongly repulsive anyons in one dimension
Florian Lange, Satoshi Ejima, Holger Fehske
To explore the static properties of the one-dimensional anyon-Hubbard model for a mean density of one particle per site, we apply perturbation theory with respect to the ratio betw…
Anyonic Haldane insulator in one dimension
Florian Lange, Satoshi Ejima, Holger Fehske
We demonstrate numerically the existence of a nontrivial topological Haldane phase for the one-dimensional extended (-) Hubbard model with a mean density of one particle per…
Spectral and Entanglement Properties of the Bosonic Haldane Insulator
Satoshi Ejima, Florian Lange, Holger Fehske
We discuss the existence of a nontrivial topological phase in one-dimensional interacting systems described by the extended Bose-Hubbard model with a mean filling of one boson per…
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…
