Fundamental role of nonlocal orders in 1D Extended Bose-Hubbard Model
Fundamental role of nonlocal orders in 1D Extended Bose-Hubbard Model
Nonlocal order parameters capture the presence of correlated fluctuations between specific degrees of freedom, in otherwise disordered quantum matter. Here we provide a further example of their fundamental role, deriving the ground state phase diagram of the filling one extended Bose Hubbard model exclusively in terms of their ordering. By …
