FewBody.jl

FewBody.jl is a Julia package for solving quantum-mechanical few-body problems. It brings together the JuliaFewBody ecosystem under a common interface, providing tools for constructing few-body Hamiltonians and accessing complementary numerical approaches such as explicitly correlated Gaussian (ECG) and variational Monte Carlo (VMC) methods.

Installation
