Temperature derivative of the superfluid density in the attractive Hubbard model.
Temperature Derivative of the Superfluid Density in the Attractive Hubbard model. Abstract Based on extensions of the grand-canonical Quantum Monte-Carlo algorithm to incorporate magnetic fields, we provide numerical data confirming the existence of a Kosterlitz-Thouless transition in the attractive Hubbard model. Here, we calculate the temperature derivative of the superfluid density, ∂βDs(β) ...
متن کاملNonperturbative approach to the attractive Hubbard model
A nonperturbative approach to the single-band attractive Hubbard model is presented in the general context of functional-derivative approaches to many-body theories. As in previous work on the repulsive model, the first step is based on a local-field-type ansatz, on enforcement of the Pauli principle and a number of crucial sumrules. The Mermin-Wagner theorem in two dimensions is automatically ...
متن کاملAccurate determination of the superfluid-insulator transition in the one-dimensional Bose-Hubbard model
The quantum phase transition point between the insulator and the superfluid phase at unit filling factor of the infinite one-dimensional Bose-Hubbard model is numerically computed with a high accuracy. The method uses the infinite system version of the time evolving block decimation algorithm, here tested in a challenging case. We provide also the accurate estimate of the phase transition point...
متن کاملThe superfluid-insulator transition in the disordered two-dimensional Bose-Hubbard model
We investigate the superfluid-insulator transition in the disordered two-dimensional Bose-Hubbard model through quantum Monte Carlo simulations. The Bose-Hubbard model is studied in the presence of site disorder and the quantum critical point between the Bose-glass and superfluid is determined in both the grand canonical (μ/U = 0.375 close to ρ = 1) and canonical ensemble (ρ = 1 and 0.5). Parti...
متن کاملSuperfluid to Mott-insulator transition in Bose-Hubbard models.
We study the superfluid-insulator transition in Bose-Hubbard models in one-, two-, and three-dimensional cubic lattices by means of a recently proposed variational wave function. In one dimension, the variational results agree with the expected Berezinskii-Kosterlitz-Thouless scenario of the interaction-driven Mott transition. In two and three dimensions, we find evidence that, across the trans...
