On the Existence of Stable Unduloids of Dimension Eight
David Hartley
In this paper we study the stability of -dimensional constant mean curvature unduloids embedded in slabs in . We prove that among the family of half period und…

Laplace operators with eigenfunctions whose nodal set is a knot
Alberto Enciso, David Hartley, Daniel Peralta-Salas
We prove that, given any knot in a compact 3-manifold M, there exists a Riemannian metric on M such that there is a complex-valued eigenfunction u of the Laplacian, correspondi…

A problem of Berry and knotted zeros in the eigenfunctions of the harmonic oscillator
Alberto Enciso, David Hartley, Daniel Peralta-Salas
We prove that, given any finite link L in R^3, there is a high energy complex-valued eigenfunction of the harmonic oscillator such that its nodal set contains a union of connected…
