Lecture notes on Monte Carlo simulations - umu.se

physics with an emphasis on Markov chain Monte Carlo and critical phe-nomena. Some simple stochastic models are also introduced; many of them have been selected because of there interesting collective behavior. The term Monte Carlo is used in the broad sense to contain all kinds of calculations that can be performed with the help of random numbers.

An Introduction to the Hubbard Hamiltonian

Monte Carlo (QMC). The objective of these notes is to provide an introduction to the HH and to a few of the most simple ways in which it is solved. Along the way we will discover that these basic calculations lend initial insight to concepts like the Mott gap, moment formation, the mapping of the HH to the Heisenberg model, and magnetism.
