SUMMARY:Tying Knots in Wavefunctions - Professor Mark Dennis (Theoretical

DESCRIPTION:Tying a knot in a piece of string can be a hard practical prob
 lem. It seems even harder to tie a field into a knot — say a function fr
 om 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 e
 xamples of knotted wavefunctions\, where the function satisfies Schröding
 er’s equation: how to design wavefunctions with specific knotted zero li
 nes\, realisable in laser beams\, and how tangled knots appear in chaotic 
 random 3D eigenfunctions.
