Photon Collisions with Atoms and Molecules
Published 2025“…This thesis focuses on the theoretical and computational study of photoionisation, Rayleigh, and Raman scattering on the alkali atoms, which can be well-approximated as quasi one-electron systems, and the hydrogen molecule H2, its ion, and its isotopologues. Photon scattering methods previously developed for the hydrogen atom are extended to quasi one-electron atoms, a fully relativistic formulation, and then to the diatomic hydrogen molecule.…”

Electromagnetic wave chaos in photonic crystals
Published 2009“…Similarities in the form of the Schrodinger equation that governs the behaviour of electronic wavefunctions, and Maxwell’s equations which govern the behaviour of electromagnetic waves, allow ideas that originated in solid state physics to be easily applied to electromagnetic waves in photonic structures. While electrons moving through a semiconductor experience a periodic variation in charge, in a photonic crystal electromagnetic waves experience a periodic variation in refractive index. …”
