The quantum-mechanical few-body challenge is of basic significance for all branches of microphysics and it has considerably broadened with the appearance of contemporary desktops. This e-book provides an easy, unified recipe to acquire distinct ideas to nearly any few-body bound-state challenge and provides its software to numerous difficulties in atomic, molecular, nuclear, subnuclear and stable kingdom physics. the most constituents of the method are a wave-function enlargement by way of correlated Gaussians and an optimization of the variational trial functionality via stochastic sampling. The ebook is written for physicists and, particularly, for graduate scholars drawn to quantum few-body physics.
