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 means …
