Gutzwiller study of extended Hubbard models with fixed boson densities
Takashi Kimura ;
Date 16 Mar 2011
AbstractWe studied all possible ground states, including supersolid (SS) phases and phase separations of hard-core and soft-core extended Bose--Hubbard models with fixed boson densities by using the Gutzwiller variational wave function. We found that the phase diagram of the soft-core model strongly depends on its transfer integral. Furthermore, for a large transfer integral, we showed that a SS phase can be the ground state even below half filling. Finally, we found that the density difference between nearest-neighbor sites, which shows the density order of the SS phase, strongly depends on the boson density, especially for a small transfer integral.
