Abstract

Exact diagonalization and quantum Monte Carlo methods are used to compute the specific heat and the charge and spin correlation functions for a two-dimensional system of correlated electrons, described by the Montorsi-Rasetti model. Our results strongly suggest the occurrence of an unusual phase transition at finite temperatures.

METAL-INSULATOR TRANSITIONS AND STRONG ELECTRON CORRELATIONS

Kristel F. L. Michielsen

An overview of lattice models for strongly correlated electrons is given. A detailed study is presented of a model recently introduced by Montorsi and Rasetti. Analytical, exact diagonalization and Quantum Monte Carlo techniques are employed to investigate the static and dynamic properties of this model. The complete ground state phase diagram of the one-, two- and three-dimensional model is given. The Montorsi-Rasetti model is shown to exhibit a metal-insulator transition of the Mott type, independent of the dimensionality of the lattice, and has a ferromagnetic phase. Results for the two-dimensional Montorsi-Rasetti model strongly suggest the occurrence of a phase transition at finite temperatures.

First-order phase transitions in the Montorsi-Rasetti model

Kristel F. L. Michielsen, Hans A. De Raedt

Exact diagonalization and quantum Monte Carlo methods are used to explore the zero-temperature phase diagram of a simplified Hubbard model extended with bond-charge--site-charge interactions. Numerical results for the grand potential and for its first derivatives with respect to the Coulomb potential and the chemical potential strongly suggest the occurrence of first-order phase transitions. It is shown that there is a close analogy between the first-order ground-state phase transitions in this quantum system and the phase transitions in classical (P,V,T) systems.

An extension of the Hubbard model, introduced by Montorsi and Rasetti, is studied using exact diagonalization and quantum Monte Carlo methods. Our numerical results for the static and dynamic properties of one- and two-dimensional systems strongly suggest the occurrence of a metal-insulator transition.

We have investigated the phase transition of two-dimensional Ising model by Monte Carlo method.Our results reveal that a finite-temperature phase transition occurs in the Ising model.The calculation result agrees well with the theoretical one.The specific heat and the susceptibility peak at the critical temperature while they descend at both high and low temperature.The spontaneous magnetization approaches to unit when the temperature is below the critical temperature.

Bond-charge–site-charge interaction and metal-insulator transitions

Kristel F. L. Michielsen

Exact-diagonalization and quantum Monte Carlo methods are used to study the occurrence of a metal-insulator transition and the distribution of charges and magnetic moments in the ground state of a one- and two-dimensional half-filled system of correlated electrons, described by a one-band simplified Hubbard model extended with bond-charge--site-charge interactions. Numerical results for the electrical conductivity, the density of states, and the spin- and charge-density correlation functions strongly suggest that the bond-charge--site-charge interaction plays a fundamental role in the occurrence of a metal-insulator transition and of ferromagnetic order.

1 Computational Studies of Quantum Spin Systems

Anders W. Sandvik

These lecture notes introduce quantum spin systems and several computational methods for studying their ground-state and finite-temperature properties. Symmetry-breaking and critical phenomena are first discussed in the simpler setting of Monte Carlo studies of classical spin systems, to illustrate finite-size scaling at continuous and first-order phase transitions. Exact diagonalization and quantum Monte Carlo (stochastic series expansion) algorithms and their computer implementations are then discussed in detail. Applications of the methods are illustrated by results for some of the most essential models in quantum magnetism, such as the S=1/2 Heisenberg antiferromagnet in one and two dimensions, as well as extended models useful for studying quantum phase transitions between antiferromagnetic and magnetically disordered states.
