Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

A twist in the universe's first light could hint that scientists need to rethink physics. A pair of Japanese scientists looked at the polarization or orientation of light from the cosmic microwave ...

A beam transformed: Optical transforms like tight focussing and total internal reflection, which gives rise to an evanescent field, can lead to out-of-plane polarization components and transverse spin ...

A new device for rotating the polarization of terahertz radiation has been created by accident by researchers in the US. While practical applications remain unclear, the discovery could boost the ...
