Certain materials have desirable properties that are hidden and scientists can use light to uncover these properties. Researchers have used an advanced optical technique, based on terahertz ...

(Nanowerk Spotlight) Light carries information in its wavelength, wavevector direction, polarization, and the way it bends through materials. Until now, optical data storage has typically used just ...

The physics department at UC Santa Barbara houses its own powerful particle accelerator that accelerates electrons to 99.4% of the speed of light: The Sherwin Group’s ability to produce short and ...

Using an improved technique that gave access to a broader range of frequencies, the team was able to uncover some of the hidden properties of the TNS exciton condensate. Certain materials have ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

Shining intense infrared laser pulses on titanium generates higher-frequency light, revealing how its optical properties change in different directions due to variations in electron movement and ...

A programmable semiconductor changes its electronic properties under UV light and reverts under a different wavelength, enabling optical writing and reading for potential computing applications.

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect ...

Many seemingly mundane materials, such as the stainless steel on refrigerators or the quartz in a countertop, harbor fascinating physics inside them. These materials are crystals, which in physics ...
