Theory redraws formation of early universe
Scientists have provided a solid foundation for an alternative theory to help explain how the early universe took shape.
View ArticleGiant atoms could help unveil 'dark matter' and other cosmic secrets
The universe is an astonishingly secretive place. Mysterious substances known as dark matter and dark energy account for some 95% of it. Despite huge effort to find out what they are, we simply don't...
View ArticleCassini, Voyager missions suggest new picture of Sun's interaction with galaxy
New data from NASA's Cassini mission, combined with measurements from the two Voyager spacecraft and NASA's Interstellar Boundary Explorer, or IBEX, suggests that our sun and planets are surrounded by...
View ArticleBreaking Newton's Law: Intriguing oscillatory back-and-forth motion of a...
A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton's equations of motion tell us that a moving body...
View ArticlePhysicists observe individual atomic collisions during diffusion for the...
In the world of research, diffusion is understood as a process in which tiny particles disperse uniformly throughout a gas or liquid. Although these media are made up of individual particles, diffusion...
View ArticleSupercool breakthrough brings new quantum benchmark
By gently prodding a swirling cloud of supercooled lithium atoms with a pair of lasers, and observing the atoms' response, researchers at Swinburne have developed a new way to probe the properties of...
View ArticleResearchers see unexplained phase shifts during atomic scattering
In an article published today (Thursday, Aug. 24) in the American Physical Society journal Physical Review Letters, researchers reported observing unexpected instantaneous phase shifts during atomic...

The sun's recent activity has caught the interest of scientists and space weather forecasters worldwide, highlighting the need to keep a watchful eye on our star and its awesome power.
View ArticleSpotting the spin of the Majorana fermion under the microscope
Researchers at Princeton University have detected a unique quantum property of an elusive particle notable for behaving simultaneously like matter and antimatter. The particle, known as the Majorana...
View ArticleRevealing quantum statistics with a pair of distant atoms
An international team of researchers has proposed a new way to make atoms or ions indistinguishable by swapping their positions. These particles are then expected to exhibit exotic properties. The...
View ArticleTwo teams independently test Tomonaga–Luttinger theory
(Phys.org)—Two teams of researchers working independently of one another have found ways to test aspects of the Tomonaga–Luttinger theory that describes interacting quantum particles in 1-D ensembles...
View ArticleNew mathematical models could help solve few-body problems in physics
In physics, the conundrum known as the "few-body problem," how three or more interacting particles behave, has bedeviled scientists for centuries. Equations that describe the physics of few-body...
View ArticleWave properties of particles can manifest in collisions
Dmitry Karlovets, senior researcher at the TSU Faculty of Physics, and Valery Serbo from the Institute of Mathematics of the SB RAS have shown that it is possible to observe the wave properties of...
View ArticlePlasma from lasers can shed light on cosmic rays, solar eruptions
Lasers that generate plasma can provide insight into bursts of subatomic particles that occur in deep space, scientists have found. Such findings could help scientists understand cosmic rays, solar...
