Researchers have identified a metal that conducts electricity without conducting heat – an incredibly useful property that defies our current understanding of how conductors work.   The metal, found in 2017, contradicts something called the Wiedemann-Franz Law, which basically states that good conductors of electricity will also be proportionally good conductors of heat, which is

Under the right circumstances, individual electrons can form partnerships that allow them to zip effortlessly through special materials called superconductors – letting them conduct electrical current without resistance.   That in itself is pretty impressive. But now physicists have found evidence these quantum partnerships – known as ‘Cooper pairs‘ – are also capable of acting

The three-body problem, one of the most notoriously complex calculations in physics, may have met its match in artificial intelligence: a new neural network promises to find solutions up to 100 million times faster than existing techniques.   First formulated by Sir Isaac Newton, the three-body problem involves calculating the movement of three gravitationally interacting

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

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

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

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

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

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

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

In the summer of 1935, the physicists Albert Einstein and Erwin Schrödinger engaged in a rich, multifaceted and sometimes fretful correspondence about the implications of the new theory of quantum mechanics.   The focus of their worry was what Schrödinger later dubbed entanglement: the inability to describe two quantum systems or particles independently, after they
