Exact 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 ...
متن کاملPolarons in the three-band Peierls-Hubbard model: An exact diagonalization study.
We have studied the three-band Peierls-Hubbard model describing the Cu-O layers in high-T c superconductors by using Lanczos diagonalization and assuming infinite mass for the ions. When the system is doped with one hole, and for λ (the electron-lattice coupling strength) greater than a critical value, we found that the oxygens around one Cu contract and the hole self-traps forming a lattice an...
متن کاملDisorder and interaction in 2D: 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 کاملQuasiparticle Undressing: a New Route to Collective Effects in Solids
The carriers of electric current in a metal are quasiparticles dressed by electronelectron interactions, which have a larger effective mass m* and a smaller quasiparticle weight z than non-interacting carriers. If the momentum dependence of the self-energy can be neglected, the effective mass enhancement and quasiparticle weight of quasiparticles at the Fermi energy are simply related by z = m/...
