Modern imaging is increasingly expected to do more than “take a picture.” In many real-world scenarios, what matters is not only the overall brightness of an object, but also where its boundaries, ...

A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a ...

Photonics is forcing EDA to verify not just chips, but the physics of light inside full electro-optical systems.

Mechanical strain is one of the most common tools used to tailor the properties of materials. In piezoelectric materials, stretching or compressing a crystal generates an electrical polarization. In ...

Many of the advanced electronic components surrounding us in everyday life rely on polar materials to function. Polar materials have an uneven distribution of electric charge. This gives them a ...

One important form is called an optical vortex beam. Unlike an ordinary light beam with a flat wavefront, an optical vortex beam has a twisted, corkscrew-like phase structure and a dark center, much ...

Russian President Vladimir Putin shakes hands with Iranian Foreign Minister Abbas Araghchi during their meeting at the Boris Yeltsin Presidential Library in Saint Petersburg on April 27, 2026. Dmitry ...

Linearly polarized light magnetism in 2D materials: Shandong University's Nano Letters study shows ordinary laser light creates a magnetic moment in wholly non-magnetic van der Waals heterobilayers ...

Researchers have created a device that enables them to control the flow of electrons through a semiconductor using only laser ...
