The Hermite functions https://en.wikipedia.org/wiki/Hermite_polynomials#Hermite_functions are fourier invariant up to scaling. How does a fourier transform invariant representation of spherical harmonics look like? The Laplace's spherical harmonics ${\displaystyle Y_{\ell }^{m}(\theta ,\varphi )}$ expanded in Hermite polynomials?
