Neutrons measured with unprecedented precision using a 'magneto-gravitational trap'
May 18, 2018 (SPX)
The study, published May 11 in the journal Science, reports a highly accurate way to measure the decay rate of neutrons. An author on the study, Chen-Yu Liu, is...
Processes in the atomic microcosmos are revealed
May 18, 2018 (SPX)
The movements of electrons in atoms were revealed using attosecond free-electron pulses. The findings of the researchers from Erlangen have been published in th...
Quarks feel the pressure in the proton
May 17, 2018 (SPX)
The nuclear physicists found that the proton's building blocks, the quarks, are subjected to a pressure of 100 decillion Pascal (1035) near the center of a prot...
ALMA and VLT find evidence for stars forming soon after Big Bang
May 17, 2018 (SPX)
The team inferred that the signal was emitted 13.3 billion years ago (or 500 million years after the Big Bang), making it the most distant oxygen ever detected ...
ALMA finds oxygen 13.28 billion light-years away
May 17, 2018 (SPX)
"Rather than saying I was happy, it would be more accurate to say I was thrilled to see the signal of the most distant oxygen," explains Takuya Hashimoto, the l...
Astronomers find fastest-growing black hole known in the universe
May 15, 2018 (SPX)
The astronomers have looked back more than 12 billion years to the early dark ages of the universe, when this supermassive black hole was estimated to be the si...
Could a multiverse be hospitable to life?
May 14, 2018 (SPX)
Questions about whether other universes might exist as part of a larger Multiverse, and if they could harbour life, are burning issues in modern cosmology. Now ...
The big bell test challenges Einstein
May 10, 2018 (SPX)
Using smartphones and other internet-connected devices, participants contributed unpredictable bits, which determined how entangled atoms, photons, and supercon...
Construction Begins on SuperCDMS Dark Matter Experiment
May 08, 2018 (SPX)
The U.S. Department of Energy has approved funding and start of construction for the SuperCDMS SNOLAB experiment, which will begin operations in the early 2020s...
Laser-driven electron recollision remembers molecular orbital structure
May 07, 2018 (SPX)
Strong infrared laser pulses can extract an electron from a molecule (ionization), accelerate it away into free space, then turn it around (propagation), and fi...
Long-distance relationships of particles: Electron-hole pairs in two-dimensional crystals
May 04, 2018 (SPX)
Yet, two-dimensional crystals host a sheer zoo of excitons, making it hard to tell the kind of excitons dealt with in specific situations. Researchers of TU Dre...
Toy-inspired experiment on behavior of quantum systems
May 03, 2018 (SPX)
Lev and his group built their own quantum version of Newton's cradle in order to answer questions about how the chaotic motion of quantum particles eventually l...
Yale physicists find signs of a time crystal
May 03, 2018 (SPX)
The discovery means there are now new puzzles to solve, in terms of how time crystals form in the first place. Ordinary crystals such as salt or quartz are exam...
Taming The Multiverse: Stephen Hawking's Final Theory About The Big Bang
May 02, 2018 (SPX)
The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far ...
'Exceptional' research points way toward quantum discoveries
May 01, 2018 (SPX)
The discovery of exceptional points in a unique material created by Kono's lab is one of several revelations in a paper that appears in Nature Photonics. These ...
A simple method etches patterns at the atomic scale
Apr 30, 2018 (SPX)
In standard lithography, a photosensitive film is deposited on a silicon wafer and a pattern called a mask is used to expose certain portions of the film. Then,...
Einstein's 'spooky action' goes massive
Apr 26, 2018 (SPX)
Nowadays, entanglement is considered a cornerstone of quantum mechanics, and it is the key resource for a host of potentially transformative quantum technologie...
Milky Way's supermassive black hole may have 'unseen' siblings
Apr 25, 2018 (SPX)
Typically, a supermassive black hole (SMBH) exists at the core of a massive galaxy. But sometimes SMBHs may "wander" throughout their host galaxy, remaining far...
Controlled nuclear transition will make clocks hugely more precise than atomic ones
Apr 25, 2018 (SPX)
The most precise modern clocks are atomic ones in which time is registered on the basis of electron transition between energy levels. Recently scientists sugges...
Physicists gain control over transitions between different states of matter
Apr 24, 2018 (SPX)
Nonlinear systems are extensively studied in a wide range of physical systems, notably in photonics. In such systems, interactions between particles lead to a w...
