Researchers simulate helium bubble behavior in fusion reactors
One of the most important challenges for successful commercialization of fusion power is the development of materials that can tolerate the extreme conditions of elevated temperatures and high particle...
View ArticleA little light interaction leaves quantum physicists beaming
A team of physicists at the University of Toronto (U of T) have taken a step toward making the essential building block of quantum computers out of pure light. Their advance, described in a paper...
View ArticleAntihydrogen at CERN, 20 years and going strong
Twenty years ago a team of scientists at CERN led by Walter Oelert succeeded in producing the first atoms made of antimatter particles.
View ArticleNASA plans twin sounding rocket launches over Norway this winter
This winter, two sounding rockets will launch through the aurora borealis over Norway to study how particles move in a region near the North Pole where Earth's magnetic field is directly connected to...
View ArticleAugerPrime looks for cosmic superaccelerators
The Pierre Auger Observatory in Argentina, an international large-scale experiment to study cosmic rays, will be continued until 2025 and extended to "AugerPrime". The observatory, for the project...
View ArticleNew insights into the creation of heavy elements: Researchers simulate...
Alpha particles, as the nuclei of the helium atom are also called, play a decisive role in the formation of heavier elements. Carbon, for instance, is formed from the fusion of these alpha particles....
View ArticlePromising cancer therapy advanced by chemical explanation
Radiation therapy: A chilling word that creates images of burn-injuries where the cancer killing ray went through the skin. For decades research hospitals have been investigating the alternative method...
View ArticleFrom MACHOs to WIMPs—meet the top five candidates for 'dark matter'
When we look out at the universe – even with the most powerful of telescopes – we can only see a fraction of the matter we know must be there. In fact, for every gram's worth of atoms in the universe,...
View ArticleWhat are the parts of an atom?
Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of...
View ArticleRecipe for muon pair creation, in theory
A true-muonium only lives for two microseconds. These atoms are made up one positively and one negatively charged elementary particle, also known as muons. Although they have yet to be observed...
View ArticleSolving hard quantum problems—everything is connected
Quantum objects cannot just be understood as the sum of their parts. This is what makes quantum calculations so complicated. Scientists at TU Wien have now calculated Bose-Einstein-condensates,...
View ArticlePhysicists measure long-range magnetic interactions between ultracold particles
In an international first, a research team of experimental physicists led by Francesca Ferlaino and theoretical physicists led by Peter Zoller has measured long-range magnetic interactions between...
View ArticleStudy reveals novel uniform coating process of p-ALD
Scientists at the U.S. Naval Research Laboratory (NRL) have devised a clever combination of materials—when used during the thin-film growth process—to reveal that particle atomic layer deposition, or...
View ArticleTwo NASA sounding-rocket missions to explore coronal nanoflares and escaping...
Why is the sun's outermost layer 1,000 times hotter than the visible surface of the sun? What are the physical mechanisms that allow oxygen atoms in Earth's atmosphere to overcome gravity and race into...
View ArticleChanges in strength of Earth's magnetic field mapped
With more than two years of measurements by ESA's Swarm satellite trio, changes in the strength of Earth's magnetic field are being mapped in detail.
View ArticleNew approach to nuclear structure, freely available
The atomic nucleus is highly complex. This complexity partly stems from the nuclear interactions in atomic nuclei, which induce strong correlations between the elementary particles, or nucleons, that...
View ArticleUK physicist who worked on Higgs boson dies: university
Tom Kibble, a leading British physicist whose work helped lead to the discovery of the Higgs boson, died Thursday aged 83, his university in London said.
View ArticleImage: Twilight stars at Concordia
Concordia sits on a plateau 3200 m above sea level. A place of extremes, temperatures can drop to –80°C in the winter, and the Sun does not rise above the horizon in the winter, forcing the crew to...
View ArticlePhysicists collide ultracold atoms to observe key quantum principle
Physicists from New Zealand's University of Otago have used steerable 'optical tweezers' to split minute clouds of ultracold atoms and slowly smash them together to directly observe a key theoretical...
