Superfluid density and quasi-long-range order in the one-dimensional disordered Bose–Hubbard model

Superfluid density and quasi-long-range order in the one-dimensional disordered Bose–Hubbard model

We study the equilibrium properties of the one-dimensional disordered Bose–Hubbard model by means of a gauge-adaptive tree tensor network variational method suitable for systems with periodic boundary conditions. We compute the superfluid stiffness and superfluid correlations close to the superfluid...
