Transverse Field Dependence of the Ground State in the Z2 Bose-Hubbard Model
Yuma Watanabe, Shohei Watabe, Tetsuro Nikuni
The study of interaction between the particle and lattice degrees of freedom is one of the central interests in the quantum many-body systems. The Z2 Bose-Hubbard model has been pr…
