Anti-Self-Dual Spacetimes, Gravitational Instantons and Knotted Zeros of the Weyl Tensor

Snigdh Sabharwal, Jan Willem Dalhuisen

We derive a superpotential for null electromagnetic fields in which the field line structure is in the form of an arbitrary torus knot. These fields are shown to correspond to sing…

Knotted optical vortices in exact solutions to Maxwell's equations

Albertus Johannes Jacobus Maria de Klerk, Roland Ivo van der Veen, Jan Willem Dalhuisen +1

We construct a family of exact solutions to Maxwell's equations in which the points of zero intensity form knotted lines topologically equivalent to a given but arbitrary algebraic…
