摘要（Abstract）：

The Hubbard model is one of the most important concepts in the theory of strongly correlated materials that offers insights into various phenomena, such as magnetism, a metal-insulator transition and superconductivity. While the behaviour of many fascinating materials can be described within the Hubbard model and its extensions, it remains one of the most difficult models to solve, and a number of various numerical techniques have been developed to simulate its properties. In this lecture, I will talk about some general aspects of the Hubbard model, its applications in the theory of magnetism, and the state-of-the-art simulation tools, such as exact diagonalization and dynamical mean-field theory.
