Pair supersolid of the extended Bose-Hubbard model with atom-pair hopping on the triangular Lattice
Wanzhou Zhang, Yancheng Wang, Wenan Guo
We systematically study an extended Bose-Hubbard model with atom hopping and atom-pair hopping in the presence of a three-body constraint on the triangular lattice. By means of lar…

Critical properties of the Hintermann-Merlini model
Chengxiang Ding, Yancheng Wang, Wanzhou Zhang +1
Many critical properties of the Hintermann-Merlini model are known exactly through the mapping to the eight-vertex model. Wu [J. Phys. C {\bf 8}, 2262 (1975)] calculated the sponta…
