Anderson localization versus charge-density-wave formation in disordered electron systems
S. Nishimoto, S. Ejima, H. Fehske
We study the interplay of disorder and interaction effects including bosonic degrees of freedom in the framework of a generic one-dimensional transport model, the Anderson-Edwards…

Phase separation in the Edwards model
S. Ejima, S. Sykora, K. W. Becker +1
The nature of charge transport within a correlated background medium can be described by spinless fermions coupled to bosons in the model introduced by Edwards. Combining numerical…

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…
