Partial Quantisation of Non-Hermitian Berry Phases in Time-Varying Media
Calvin Hooper
A fundamental symmetry of the non-Hermitian operators describing wave-propagation in time-varying media imbue such systems with non-trivial topology. This topology may be measured…

Scattering in Time-Varying Drude-Lorentz Models
Bryce Dixon, Calvin M. Hooper, Ian R. Hooper +1
Motivated by recent experiments, the theoretical study of wave propagation in time varying materials is of current interest. Although significant in nearly all such experiments, ma…

Quasi Normal Modes in Dispersive Photonic Time-Crystals
Calvin M. Hooper, Ian R. Hooper, Simon A. R. Horsley
Quasinormal modes characterise the transient response of static optical cavities. Here, we introduce the notion of a Floquet quasinormal mode to describe transient responses in pho…
