ISOA v9.0 — Deterministic Spectral Hamiltonian Propagator

Abstract

ISOA v9.0 is a deterministic spectral split-step Fourier solver for the time-dependent Schrödinger equation. The method is unitary, second-order accurate in time, and achieves O(N log N) complexity via FFT-based Hamiltonian propagation. The implementation emphasizes numerical stability, strict norm conservation, and reproducible benchmarking. This release includes:• core Python solver• conservation, convergence, and runtime experiments• reproducible figures• minimal documentation Designed for research and educational use in computational physics and spectral methods.
