Abstract

Over the last decade, Quantum Monte Carlo (QMC) calculations for tight binding Hamiltonians like the Hubbard and Anderson lattice models have made the transition from addressing abstract issues concerning the effects of electron-electron correlations on magnetic and metal-insulator transitions, to concrete contact with experiment. This paper presents results of applications of “determinant” QMC to systems with disorder such as the conductivity of thin metallic films, the behavior of the magnetic susceptibility in doped semiconductors, and Zn doped cuprate superconductors. Finally, preliminary attempts to model the Kondo volume collapse in rare earth materials are discussed.

17. While we have used the term “site” for the indices i and j, these can in fact also label different orbitals. From a technical viewpoint, the determinant QMC algorithm treats distinct sites and orbitals in precisely the same way. They differ only in the Hamiltonian itself, that is in the choice of t ij, U i, and μi.Google Scholar

19. Naively the algorithm should scale as the fourth power of the number of sites N, since for each move of one of the NL Hubbard-Stratonovich fields, a calculation of the determinant requires N 3 operations. However, a trick reduces this by one power of N.Google Scholar
