Title: An exactly solvable quantum four-body problem associated with the symmetries of an octacube

Abstract: In this presentation, I show that eigenenergies and eigenstates of a system consisting of four one-dimensional hard-core particles with masses 6m, 2m, m, and 3m in a hard-wall box can be found exactly using Bethe ansatz. The ansatz is based on the exceptional affine reflection group F_4 associated with the symmetries and tiling properties of an octacube---a Platonic solid unique to four dimensions, with no three-dimensional analogues.
