Charles Angas Hurst AM DSc FAA (22 September 1923 – 19 October 2011[1]) was an Australian mathematical physicist noted for his work in lattice models, quantum field theory, asymptotic expansions and Lie groups.
He was appointed a Member of the Order of Australia in 2003, elected a Fellow of the Australian Academy of Science in 1972, and awarded the Centenary Medal and an Hon DSc (Melb).
In 1952 Hurst represented Australia in the inaugural International Mathematical Union.
[citation needed] Hurst's work with Herbert Green[4] on lattice problems and the Ising model led to the Free fermion field model,[5] which contained all known properties of Fermions at the time of its publication.
Hurst's work with Thirring (Thirring model) found the simplest non-linear field and is still used as a test model for perturbation theory.
