A new Curtin University-created database of electron-molecule reactions is a major step forward in making nuclear fusion power a reality, by allowing researchers to accurately model plasmas containing molecular hydrogen.
Australian researchers have located the 'sweet spot' for positioning qubits in silicon to scale up atom-based quantum processors.
The Borexino experiment research team has succeeded in detecting neutrinos from the sun's second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time. This means that all of the theoretical predictions on how energy is generated within the sun have now also been experimentally verified. The findings are the result of years of efforts devoted to bringing the background sources in the energy range of the CNO neutrinos under control.
The magic of mathematics is particularly reflected in magic squares. Recently, quantum physicist Gemma De las Cuevas and mathematicians Tim Netzer and Tom Drescher introduced the notion of the quantum magic square, and for the first time studied in detail the properties of this quantum version of magic squares.
Faster, smaller, smarter and more energy-efficient chips for everything from consumer electronics to big data to brain-inspired computing could soon be on the way after engineers at The University of Texas at Austin created the smallest memory device yet.
Oscillatory behaviors are ubiquitous in Nature, ranging from the orbits of planets to the periodic motion of a swing. In pure crystalline systems, presenting a perfect spatially-periodic structure, the fundamental laws of quantum physics predict a remarkable and counter-intuitive oscillatory behavior: when subjected to a weak electric force, the electrons in the material do not undergo a net drift, but rather oscillate in space, a phenomenon known as Bloch oscillations.
Using x-ray lasers, researchers at Stockholm University have been able to follow the transformation between two distinct different liquid states of water, both being made of H2O molecules. At around -63 Centigrade the two liquids exist at different pressure regimes with a density difference of 20%. By rapidly varying the pressure before the sample could freeze, it was possible to observe one liquid changing into the other in real time. Their findings are published in the journal Science.
Bringing huge amounts of protons up to speed in the shortest distance in fractions of a second -- that's what laser acceleration technology, greatly improved in recent years, can do. An international research team from the GSI Helmholtzzentrum für Schwerionenforschung and the Helmholtz Institute Jena, a branch of GSI, in collaboration with the Lawrence Livermore National Laboratory, USA, has succeeded in using protons accelerated with the GSI high-power laser PHELIX to split other nuclei and to analyze them.
Scientists at The University of Tokyo used electron spectroscopy to probe the coordination structures formed by the silicon atoms in aluminosilicate glass. This work may lead to innovations in the touchscreen and solar panel sectors.
JILA researchers have used a state-of-the-art atomic clock to narrow the search for elusive dark matter, an example of how continual improvements in clocks have value beyond timekeeping.
