A single photon reveals quantum entanglement of 16 million atoms
Oct 18, 2017 (SPX)
The laws of quantum physics allow to emit signals and immediately detect when they are intercepted by a third party. This property is crucial for data protectio...
Filling the early universe with knots can explain why the world is three-dimensional
Oct 17, 2017 (SPX)
An international team of physicists has developed an out-of-the-box theory which proposes that shortly after it popped into existence 13.8 billion years ago the...
Energy against the current on a quantum scale, without contradicting the laws of physics
Oct 09, 2017 (SPX)
In macroscopic objects such as a current of water, the fact of observing the current does not affect the flow of the water and, in accordance with the laws of c...
What can be discovered at the junction of physics and chemistry?
Oct 09, 2017 (SPX)
These are paramagnetic molecules from the class porphyrins. Porphyrins are part of hemoglobin and chlorophyll and are closely related to the processes of photos...
Electron behavior under extreme conditions described for the first time
Oct 09, 2017 (SPX)
The work could provide insights into the behaviour of matter in fusion experiments, which may one day lead to a sought-after source of clean energy. Electrons a...
JILA's 3-D quantum gas atomic clock offers new dimensions in measurement
Oct 09, 2017 (SPX)
With so many atoms completely immobilized in place, JILA's cubic quantum gas clock sets a record for a value called "quality factor" and the resulting measureme...
What Earth's climate system and topological insulators have in common
Oct 09, 2017 (SPX)
"These waves were discovered by geophysicists in the 1960s, but they lacked a deep understanding of why they existed," said Brad Marston, a physics professor at...
Generating terahertz radiation from water makes 'the impossible, possible'
Oct 06, 2017 (SPX)
Now, as reported in a paper published in Applied Physics Letters, researchers at the University of Rochester have "made the impossible, possible," says Zhang, t...
Open-access collider data confirm subatomic particle patterns
Oct 06, 2017 (SPX)
The data, recorded and processed throughout the year 2010, amounted to about 29 terabytes of information, yielded from 300 million individual collisions of high...
Breaking the rules: Heavy chemical elements alter theory of quantum mechanics
Oct 05, 2017 (SPX)
Florida State University researchers found that the theory of quantum mechanics does not adequately explain how the heaviest and rarest elements found at the en...
We're not living in a simulation, scientists confirm
Oct 04, 2017 (UPI)
But new research by a pair of theoretical physicists suggests it is simply not possible to build a computer big enough to run such a massive simulation. Zohar R...
Team led by graduate student at PPPL produces unique simulation of magnetic reconnection
Oct 03, 2017 (SPX)
The new simulation captures the physics of magnetic reconnection, the breaking apart and snapping together of the magnetic field lines in plasma that occurs thr...
The material that obscures supermassive black holes
Oct 03, 2017 (SPX)
This feedback can take place in different forms: the AGN can heat, disrupt, consume and remove the gas available to form new stars, preventing further galaxy gr...
Supersonic gas streams from Big Bang drive massive black hole formation
Oct 03, 2017 (SPX)
"This is significant progress. The origin of the monstrous black holes has been a long-standing mystery and now we have a solution to it," said author and Kavli...
A preparative-scale reaction using platinum clusters with a single-digit atomicity realized
Sep 27, 2017 (SPX)
While several different synthesis methods have been developed from multi-nuclear metal complexes or stable ligand-protected "magic number" clusters, the precurs...
Two Stars, Three Dimensions, and Oodles of Energy
Sep 27, 2017 (SPX)
V745 Sco is a binary star system that consists of a red giant star and a white dwarf locked together by gravity. These two stellar objects orbit so closely arou...
Ravenous Black Holes Define Type I Active Galaxies
Sep 27, 2017 (SPX)
New research from an international team of astronomers, with contributions from the University of Maryland, makes a major modification to a popular theory calle...
Quantum twisted Loong confirms the physical reality of wavefunctions
Sep 25, 2017 (SPX)
However, the debate on the following deeper philosophical issue behind it still persists: whether wavefunctions describe the reality of quantum entities' existe...
Mathematicians develop new models to describe ripples
Sep 20, 2017 (UPI)
Undular bore involves the propagation of rapid oscillations. The ripple-like disturbance can occur in water or plasmas, on large or small scales. Undular bore i...
Physicists discover super stable tri-anion particle
Sep 18, 2017 (UPI)
The new particle is extremely stable and its discovery apply to a variety of applications in the fields of physics and chemistry. The imbalance between electron...
