FewBodyToolkit.jl: Solving 2- and 3-body quantum systems in 1D–3D with general potentials
2026-08-12 , Room 5

FewBodyToolkit.jl is a Julia package for solving quantum few-body problems with two and three particles in one to three dimensions. It supports pair interactions of general shape, bound and resonant states, and on-the-fly calculation of observables. The package has been applied in research on ultracold atomic systems and hadron physics, providing a unified framework for diverse few-body applications.


FewBodyToolkit.jl is a Julia package for solving quantum few-body problems with two and three particles in one to three dimensions. It supports pair interactions of general shape, bound and resonant states, and on-the-fly calculation of observables. The package has been applied in research on ultracold atomic systems and hadron physics, providing a unified framework for diverse few-body applications. In this talk, I will give an overview of its main features, selected implementation aspects, and future development plans.

I am a postdoctoral researcher (SPDR) at RIKEN in Japan. My research focuses on quantum physics, especially few-body physics, but I like to discuss about anything.
