This book presents an introduction to some of the most advanced and powerful numerical methods currently available to simulate many-particle systems. The problems treated include equilibrium and nonequilibrium properties of systems (both classical and quantum) and the interaction of charged particles with electromagnetic fields. Among the computational methods  presented are classical and path integral Monte Carlo, classical, quantum and relativistic kinetic equations, molecular dynamics and particle in cell simulations, density functional and lattice gauge theory approaches. Written by experts in computational physics and specialists in a variety of fields, this introductory book has almost everything needed to start programming, with many little details that are usually omitted in original literature.


graduate students, teachers, researchers, engineers, who are interested in numerical modeling.
