Ultimately, it showcases that Quantum Monte Carlo isn't just a numerical tool—it's an expedition that reveals the hidden facets of the quantum world. Part of IOP Series in Quantum Technology. Key features • Accompanying code and worked examples of how an algorithm can be coded and tested. • What makes Quantum Monte Carlo superior and just as importantly, what breaks it. • Teaches statistical physics and quantum physics in parallel. • Includes detailed mathematical derivations that won’t leave blind spots. • Emphasises Quantum Monte Carlo as a tool of visualizing quantum mechanics
Featuring detailed explanations of the major algorithms used in quantum Monte Carlo simulations, this is the first textbook of its kind to provide a pedagogical overview of the field and its applications. The book provides a comprehensive introduction to the Monte Carlo method, its use, and its foundations, and examines algorithms for the simulation of quantum many-body lattice problems at finite and zero temperature. These algorithms include continuous-time loop and cluster algorithms for quantum spins, determinant methods for simulating fermions, power methods for computing ground and excited states, and the variational Monte Carlo method. Also discussed are continuous-time algorithms for quantum impurity models and their use within dynamical mean-field theory, along with algorithms for analytically continuing imaginary-time quantum Monte Carlo data. The parallelization of Monte Carlo simulations is also addressed. This is an essential resource for graduate students, teachers, and researchers interested in quantum Monte Carlo techniques.
