Abstract
We prove that, given any finite link in , there is a high-energy complex-valued eigenfunction of the harmonic oscillator such that its nodal set contains a union of connected components diffeomorphic to . This solves a problem of Berry on the existence of knotted zeros in bound states of a quantum system.
