Scientists have observed a quantum vibration at normal room temperature for the first time, a phenomenon that usually requires ultra-cold, carefully calibrated conditions – bringing us another step closer to understanding the behaviour of quantum mechanics in common materials. The team was able to spot a phonon, a quantum particle of vibration generated from high-frequency

Superconductivity (passing charges through materials without losing heat) promises to revolutionise electronics and power, if we can get it working at reasonable temperatures – and scientists just reported a big step forward in our understanding of the phenomenon. The new discovery centres around the Hubbard model: a maths model of conduction and insulation in materials,

For several years now, physicists at the European Organisation for Nuclear Research (CERN) have been running a landmark experiment, recording tens of billions of particles break apart in the hopes of catching a few oddballs. And they finally have some intriguing results to share. This experiment, called NA62, has researchers building and destroying pairs of quarks called

A team of researchers has just demonstrated quantum enhancement in an actual X-ray machine, achieving the desirable goal of eliminating background noise for precision detection. The relationships between photon pairs on quantum scales can be exploited to create sharper, higher-resolution images than classical optics. This emerging field is called quantum imaging, and it has some

Scientists have found evidence of superconductivity happening at temperatures and energy levels way above its normal boundaries – a finding which could one day go on to help revolutionise the design and workings of our electronics. A superconductor material is one that can transfer electricity without resistance. In turn, this means the electricity travels through

Scientists have just discovered something new about gold. When extreme crushing pressure is applied quickly, over mere nanoseconds, the element’s atomic structure changes, becoming more similar to metals harder than gold. It’s the first time this structural state has ever been observed in gold, suggesting properties that could help scientists refine their understanding of how

Physicists in the US have discovered a material that could qualify as the first known three-dimensional example of a quantum spin liquid – an exotic theoretical phase of matter. Quantum spin liquids were first predicted by scientists back in the 1970s. While researchers have studied them for decades, these phases largely remain a theoretical concept, although

Hidden underneath the Naryn-Kala fortress in Derbent, Russia, is a mysterious subterranean vault – a buried structure whose original purpose has been unknown for decades. Now, thanks to clever use of scanning technology, we might finally know what the building is. Researchers used a nuclear physics technology known as muon radiography. It works by tracking the charged
