Weyl points and exceptional rings with polaritons in bulk semiconductors
R. L. Mc Guinness, P. R. Eastham
Weyl points are the simplest topologically-protected degeneracy in a three-dimensional dispersion relation. The realization of Weyl semimetals in photonic crystals has allowed thes…

Chern numbers for the index surfaces of photonic crystals: conical refraction as a basis for topological materials
R. L. Mc Guinness, P. R. Eastham
The classification of bandstructures by topological invariants provides a powerful tool for understanding phenomena such as the quantum Hall effect. This classification was origina…
