A surprising effect was discovered through a collaborative study by researchers from TU Wien and institutions in Croatia, France, Poland, Singapore, Switzerland, and the US during the investigation of a special material: the atoms are arranged in a completely disordered manner but produce magnetic order.

Light is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many technologies that affect our daily lives, including energy harvesting with solar cells, light-emitting-diode (LED) displays and telecommunications through fiber optic networks.

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the hypothetical force shaping the universe sprang from particles that rapidly condensed, like steam into water.

Scientists have developed a dual-laser Brillouin optical correlation-domain reflectometry (BOCDR) system that uses two frequency-modulated lasers. By scanning the relative modulation phase between the pump and reference lasers, the setup measures strain and temperature all along an optical fiber. In a proof-of-concept test on a 13-meter silica fiber, the team recorded Brillouin gain spectra (BGS) […]

By breaking away from the laws of classical physics, quantum physics has opened the door to describing the behavior of atoms and particles. This science, which explores the most fundamental building blocks of nature, relies in particular on the ability to measure their individual and collective properties.

Butterflies’ flight trajectories often appear random or chaotic, and compared with other hovering insects, their bodies follow seemingly mysterious, jagged, jerking motions.

While many research groups worldwide have been searching for dark matter over the past decades, detecting it has so far proved very challenging, thus very little is known about its possible composition and physical properties. Two promising dark matter candidates (i.e., hypothetical particles that dark matter could be made of) are axions and dark photons. […]

A team of researchers has developed a technique that makes high-dimensional quantum information encoded in light more practical and reliable.
