An achiral metasurface selectively transmits two beams of opposite chirality. Read More »
Researchers have characterized the temperature-induced frequency shifts of a thorium-229 nuclear transition—an important step in establishing thorium clocks as next-generation frequency standards. Read More »
Simulations demonstrate that light can be confined within a scattering medium in a way similar to electrons in a disordered metal. Read More »
The experiment provided further proof of the reality of photons, yet Millikan didn’t accept their existence until later in his career. Read More »
A proposed method could detect vortex states of high-energy particles through a scattering phenomenon called a superkick. Read More »
A laser-driven electron accelerator delivers beams of ∼10-GeV electrons—an approach that could lead to cheaper, more compact alternatives to large-scale x-ray sources and particle accelerators. Read More »
Through its interactions with a crystal, light becomes an opaque object—an effect that could be harnessed in applications. Read More »
A proposed remote-sensing scheme could potentially probe targets hundreds of kilometers away and uses one of the strangest quantum properties of light. Read More »
Forces imposed by laser light can manipulate the shape of a membrane’s vibrational modes. Read More »
Contrary to conventional wisdom, a lattice of engineered nanoparticles called meta-atoms can have a chiral optical response even when each meta-atom is not chiral. Read More »
