Abstract

Lipkin’s zilches are a set of little-known conserved quantities in classical

zilches for topologically non-trivial vacuum electromagnetic fields and their

the fields. Several families of electromagnetic fields have been explored and

written in terms of more familiar conserved quantities: energy, momentum

contain information about the topology of the field lines for the fields we

interpretation. We conjecture that these properties generalise to all integrable

fields.
