Abstract
Tying a knot in a piece of string can be a hard practical problem. It seems even harder to tie a field into a knot — say a function from real 3-dimensional space to the complex numbers such that the function is zero on a curve which is a given knot or link. I will talk about some examples of knotted wavefunctions, where the function satisfies Schrödinger’s equation: how to design wavefunctions with specific knotted zero lines, realisable in laser beams, and how tangled knots appear in chaotic random 3D eigenfunctions.
