Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

The exciting discovery of topological condensed matter systems has lately triggered a
search for their photonic analogues, motivated by the possibility of robust backscattering …

Fluids in which both time reversal and parity are broken can display a dissipationless
viscosity that is odd under each of these symmetries. Here, we show how this odd viscosity …

We examine the momentum, spin, and orbital angular momentum of structured
monochromatic optical fields in dispersive inhomogeneous isotropic media. There are two …

Metals, semiconductors, metamaterials, and various two-dimensional materials with
plasmonic dispersion exhibit numerous exotic physical effects in the presence of an external …

Maxwell electromagnetism, describing the wave properties of light, was formulated 150
years ago. More than 60 years ago it was shown that interfaces between optical media …

We report the existence of Weyl points in a class of noncentral symmetric metamaterials,
which has time reversal symmetry, but does not have inversion symmetry due to chiral …

We examine the momentum and angular momentum (AM) properties of monochromatic
optical fields in dispersive and inhomogeneous isotropic media, using the Abraham-and …

Classical wave fields are real-valued, ensuring the wave states at opposite frequencies and
momenta to be inherently identical. Such a particle–hole symmetry can open up new …
