Mapping supermassive black holes in the distant Universe
May 22, 2017 (SPX)
The map precisely measures the expansion history of the universe back to when the universe was less than three billion years old. It will help improve our under...
Destruction of a quantum monopole observed
May 19, 2017 (SPX)
The new study provided a surprise: the quantum monopole decays into another analogue of the magnetic monopole. The obtained fundamental understanding of monopol...
Interaction between the atomic nucleus and the electron on trial
May 18, 2017 (SPX)
At the surface of the nuclei of bismuth atoms, magnetic fields exist which are otherwise only present at the surface of massive neutron stars. The behavior of e...
Elusive atomic motion captured by electron microscopy
May 16, 2017 (SPX)
In some contexts, it is extremely important that boundaries are maintained. One example is within thin film technology, which uses extremely thin films of vario...
Unpolarized single-photon generation with true randomness from diamond
May 16, 2017 (SPX)
Quantum information technology, such as quantum computing and quantum cryptography, has the potential to exceed classical information technology in security and...
What drives the accelerating expansion of the universe
May 16, 2017 (SPX)
PhD student Qingdi Wang has tackled this question in a new study that tries to resolve a major incompatibility issue between two of the most successful theories...
'Fire-streaks' are created in collisions of atomic nuclei
May 12, 2017 (SPX)
When two massive atomic nuclei collide at high energies, the most exotic form of matter is formed: the quark-gluon plasma behaving like a perfect fluid. The the...
Astronomers Pursue Renegade Supermassive Black Hole
May 12, 2017 (SPX)
This possible renegade black hole, which contains about 160 million times the mass of our Sun, is located in an elliptical galaxy about 3.9 billion light years ...
Discovery in the Early Universe Poses Black Hole Growth Puzzle
May 12, 2017 (SPX)
At least some phases of vigorous growth are highly visible to astronomical observers: Whenever there are substantial amounts of gas swirling into the black hole...
Researchers develop transistors that can switch between 2 stable energy states
May 11, 2017 (SPX)
Modern computers are limited by a delay formed as electrons travel through the tiny wires and switches on a computer chip. To overcome this electronic backlog, ...
Controlling charged molecules with quantum logic
May 11, 2017 (SPX)
The new technique achieves an elusive goal, controlling molecules as effectively as laser cooling and other techniques can control atoms. Quantum control of ato...
Merging galaxies have enshrouded black holes
May 10, 2017 (JPL)
A merger of two galaxies is one such disruption. As the galaxies combine and their central black holes approach each other, gas and dust in the vicinity are pus...
Sandia develops math techniques to improve computational efficiency in quantum chemistry
May 09, 2017 (SPX)
Mathematical and algorithmic developments along these lines are necessary for enabling the detailed study of complex hydrocarbon molecules that are relevant in ...
CCNY physicists demonstrate photonic hypercrystals for control of light-matter interaction
May 08, 2017 (SPX)
This could lead to such benefits as ultrafast LEDs for Li-Fi (a wireless technology that transmits high-speed data using visible light communication), enhanced ...
Physicists breeding Schroedinger cat states
May 03, 2017 (SPX)
The study was published in Nature Photonics. In 1935, German physicist Erwin Schrodinger proposed a thought experiment where a cat, hidden from the observer, is...
Towards largest-possible separation between quantum and classical query complexities
May 02, 2017 (SPX)
The related research entitled "Experimental study of Forrelation in nuclear spins" was published on Science Bulletin of volume 62 and pages 497, 2017. Four scho...
Mapping the edge of reality
May 02, 2017 (SPX)
Dr Alberto Peruzzo from RMIT University in Melbourne said: "Bell's theorem excludes classical concepts of causality and is now a cornerstone of modern physics. ...
Perfect pitch: Scientists explore the mechanics of throwing
May 01, 2017 (UPI)
Researchers at Harvard University wanted to find out which kinds of throwing mechanics yield the most accurate throws. "There are many different ways to get an ...
Looking for the quantum frontier
May 01, 2017 (SPX)
"Until recently it has been difficult to say definitively when quantum computers can outperform classical computers," said Professor Michael Bremner, Chief Inve...
Mathematical model of a TARDIS takes the 'fiction' out of science fiction
Apr 28, 2017 (SPX)
Ben Tippett, a mathematics and physics instructor at UBC's Okanagan campus, recently published a study about the feasibility of time travel. Tippett, whose fiel...
