Researchers discover photonic snake states, a new instrument for unveiling the secrets of light
Light, with its countless colors, is one of the wonders of nature. To truly understand what we see, it is essential to know the precise colors of the light with which we perceive our world. We achieve this by means of optical rules called frequency c.....»»
Lavish tomb in ancient Spain belonged to a woman, not a man, new research shows
When archaeologists first discovered the 5,000-year-old ornate tomb in Spain, they assumed it was for a man. It held a rock crystal dagger, ivory tusks and other lavish items. But now they've determined the remains are those of a woman, and all it to.....»»
Multi-dimensional band structure spectroscopy in the photonic synthetic frequency dimension
In the photonic synthetic dimension, the coupling of internal degrees of freedom of photons, such as frequency, spatial mode, and orbital angular momentum, generates extra dimensions in addition to real space. This approach is a powerful tool to inve.....»»
An inhomogeneous Dirac cone system gives rise to in-plane chiral Landau levels
Chiral zeroth Landau levels are topologically protected bulk states that propagate in a single direction. In the field of quantum field theory and condensed matter physics, these levels are crucial for breaking chiral symmetry and triggering the chir.....»»
Photonic time crystals could open the door to a new branch of optics
Refractive index—the ratio of the speed of electromagnetic radiation in a medium to its speed in a vacuum—can be modulated fast enough to generate photonic time crystals (PTCs) in the near-visible part of the spectrum, a new study published in th.....»»
