CANONICAL TRANSFORMATION OF THE HUBBARD MODEL AND W=0 PAIRING: COMPARISON WITH EXACT DIAGONALIZATION RESULTS MICHELE CINI, ADALBERTO BALZAROTTI RAFFAELLA BRUNETTI, MARIA GIMELLI and GIANLUCA STEFANUCCI
We have recently developed a canonical transformation of the Hubbard and related models, valid for systems of arbitrary size and for the full plane; this is particularly suited to study hole pairing. In this work we show that exact diagonalization results of the one band Hubbard model for small clusters with periodic boundary conditions agree well with the analytical ones obtained by means of o...
متن کاملComparison of Calculations for the Hubbard model obtained with Quantum-Monte-Carlo, exact and stochastic Diagonalization
In this paper we compare numerical results for the ground state of the Hubbard model obtained by Quantum-Monte-Carlo simulations with results from exact and stochastic diagonalizations. We find good agreement for the ground state energy and superconducting correlations for both, the repulsive and attractive Hubbard model. Special emphasis lies on the superconducting correlations in the repulsiv...
متن کامل0 Disorder and Interaction in 2 D : Exact diagonalization study of the Anderson - Hubbard - Mott model
We investigate, by numerically calculating the charge stiffness, the effects of random diagonal disorder and electron-electron interaction on the nature of the ground state in the 2D Hubbard model through the finite size exact diagonalization technique. By comparing with the corresponding 1D Hubbard model results and by using heuristic arguments we conclude that it is unlikely that there is a 2...
متن کاملCanonical Transformation of the Three-Band Hubbard Model and Hole Pairing
We propose a canonical tranformation approach to the effective interaction Weff between two holes, based on the three-band Hubbard model but ready to include extra interactions as well. An effective two-body Hamiltonian can in principle be obtained including any kind of virtual intermediate states. We derive the closed-form analytic expression of the effective interaction including 4-body virtu...
متن کاملExact diagonalization: the Bose–Hubbard model as an example
We take the Bose–Hubbard model to illustrate exact diagonalization techniques in a pedagogical way. We follow the route of first generating all the basis vectors, then setting up the Hamiltonian matrix with respect to this basis and finally using the Lanczos algorithm to solve low lying eigenstates and eigenvalues. Emphasis is placed on how to enumerate all the basis vectors and how to use the ...
