Observation of symmetry breaking in time-varying scattering systems
Miguel Verde, David Globosits, Thomas F. Allard +5
From the Higgs mechanism to magnetic ordering, spontaneous symmetry breaking organizes physics across scales. Whether an analogous transition governs waves scattered by periodicall…

Switchable selective backscatter modulation via the Kerker effect
K. J. Cowan, C. M. Hooper, C. P. Gallagher +3
We design a reflective scatterer that operates only in the backscatter direction using modulation of the Kerker effect. This being a phenomena where the resonant modes of a scatter…

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…
