Of particular interest is the Haldane insulating phase which we show to be present only for density p = 1. We also show that the supersolid phase is present for a wide range of parameters including commensurate densities. | Source Title: | Journal of Physics: Conference Series | URI: | https://scholarbank.nus.edu.sg/handle/10635/180884 | ISSN: | 17426588 | DOI: | 10.1088/1742-6596/640/1/012042 | Rights: | Attribution 4.0 International |
