Multiorbital Hubbard model in infinite dimensions: Quantum Monte Carlo calculation
Using the quantum Monte Carlo technique we compute thermodynamics and spectra for the orbitally degenerate Hubbard model in infinite spatial dimensions. With increasing orbital degeneracy we find in the one-particle spectra broader Hubbard bands ~consistent with increased kinetic energy!, a narrowing Mott gap, and increasing quasiparticle spectral weight. Hund’s rule exchange coupling decreases...
متن کاملQuantum Monte Carlo evidence for superconductivity in the three-band hubbard Model in Two Dimensions.
A possibility of the electronic origin of the high-temperature superconductivity in cuprates is probed with the quantum Monte Carlo method by revisiting the three-band Hubbard model comprising Cu3dx2−y2 and O2pσ orbitals. The dx2−y2 pairing correlation is found to turn into an increasing function of the repulsion Ud within the d orbitals or the d-p level off-set ∆ε, where the correlation grows ...
متن کاملImaginary-chemical-potential quantum Monte Carlo method for Hubbard molecules.
We generalize the imaginary-chemical-potential quantum Monte Carlo (QMC) method proposed by Dagotto [Phys. Rev. B 41, R811 (1990)] to systems without particle-hole symmetry. The generalized method is tested by comparing the results of the QMC simulations and exact diagonalization on small Hubbard molecules, such as tetrahedron and truncated tetrahedron. Results of the application of the method ...
متن کاملMott – Hubbard Insulator in Infinite Dimensions ∗
We calculate the one-particle density of states for the Mott–Hubbard insulating phase of the Hubbard model on a Bethe lattice in the limit of infinite coordination number. We employ the Kato–Takahashi perturbation theory around the strong-coupling limit to derive the Green function. We show that the Green function for the lower Hubbard band can be expressed in terms of polynomials in the bare h...
