Description
Summary:In this work, we derive three recursive formulas for the integrals of products of Hermite polynomials. The derivation is notably straightforward, relying solely on the well-established properties of Hermite polynomials and the technique of integration by parts. These results hold broad relevance across various fields of physics and mathematics. Specifically, they would be applied to accurately compute two- and three-body matrix elements in ab initio simulations of one-dimensional few-body systems confined in harmonic traps. Additionally, we provide a numerical subroutine that implements these recursive formulas, which accompanies this work.
