An international team has demonstrated a new method for producing the most intense light ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Scientists have achieved a breakthrough in light manipulation by using topological insulators to generate both even and odd terahertz frequencies through high-order harmonic generation (HHG). By ...

Laser-plasma interactions represent a cornerstone of high-energy-density physics, where intense laser pulses interact with solid or gaseous targets to generate plasmas. This process underpins the ...

A single gold nanorod, far smaller than a wavelength of visible light, can be coaxed into emitting circularly polarized ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave or a particle. Columnist Karmela Padavic-Callaghan finds that the matter ha ...

The continuous development of bright, stable and highly coherent high-energy light sources is a propellant to the fields of material science, biomedical imaging, ultrafast spectroscopy, and industrial ...

Thanks to modern LED bulbs, light is cheaper than ever to make—except for one particular kind. Three University of Chicago scientists have announced an innovative way to create infrared light, which ...

For the first time, researchers measured singularities in combined light and sound waves moving faster than the speed of ...

Researchers generated stable vortex light in its lowest-energy state using liquid crystal traps and optical confinement.
