Angular Momentum Fluctuations in the Phonon Vacuum of Symmetric Crystals
Rule Yi, Violet Williams, Benedetta Flebus
Although time-reversal and inversion symmetry constrain the angular momentum of each phonon mode to vanish, we show that the vacuum state of crystals with such symmetries can never…

Transmission anomalies in 2D photonic crystals from the checkerboard family: From broken to hidden symmetries and plasmon "spoofing"
T. Dodge, M. Schiller, R. Yi +2
In a field representation, the main symmetry of the electromagnetic response of complementary metal film structures is described by the Babinet principle, expected to be obeyed by…
