Diffusion Quantum Monte Carlo algorithms

The Diffusion Quantum Monte Carlo (DQMC) algorithm and related methods such as the Vibrational Quantum Monte Carlo approach have the important property of scahng well with system size (number of degrees of freedom). At the same time the method can be pursued in principle to yield a numerically exact energy. DQMC was introduced... [Pg.172]

The material presented above was selected to describe from a unified point of view Monte Carlo algorithms as employed in seemingly unrelated areas in quantum and statistical mechanics. Details of applications were given only to explain general ideas or important technical problems, such as encountered in diffusion Monte Carlo. We ignored a whole body of literature, but we wish to just mention a few topics. Domain Green function Monte Carlo [25-28] is one that comes very close to topics that were... [Pg.111]
