One-dimensional Hubbard-Holstein model with finite range electron-phonon coupling
F. Hébert, Bo Xiao, V. G. Rousseau +2
The Hubbard-Holstein model describes fermions on a discrete lattice, with on-site repulsion between fermions and a coupling to phonons that are localized on sites. Generally, at ha…

Hatano-Nelson model with a periodic potential
F. Hébert, M. Schram, R. T. Scalettar +2
We study a generalisation of the Hatano-Nelson Hamiltonian in which a periodic modulation of the site energies is present in addition to the usual random distribution. The system c…

Supersolids in the Bose-Hubbard Hamiltonian
G. G. Batrouni, R. T. Scalettar, G. T. Zimanyi +1
We use a combination of numeric and analytic techniques to determine the groun d state phase diagram of the Bose--Hubbard Hamiltonian with longer range repulsi ve interactions. At…
