Shuhei Ohno
I am a Ph.D. candidate at Yokohama City University and a junior research associate (JRA) at RIKEN in Japan. I launched JuliaFewBody for developing FewBody.jl, general-purpose flexible solvers for quantum mechanical few-body problems. At JuliaCon 2025, I presented several of his packages towards completing FewBody.jl.
I am the organizer of several events related to Julia and computational physics:
- Julia in Physics 2024,
- JuliaLang Japan 2025,
- Spring School on Computational Physics,
- Computational Physics Hackathon 2026 (CompPhysHack2026).
Session
Open-source software (OSS) is a practical way to ensure reproducibility and avoid reinventing the wheel in computational physics. In particular, few-body systems physics has various targets and various software requirements, so we are building an open-source ecosystem in Julia as a shared infrastructure with reusability and extensibility. In this talk, we introduce the architectural design and development roadmap derived from system-level testability and report the current development status.
