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.
A team of researchers led by Berkeley Lab has developed a method to fabricate a one-dimensional array of individual molecules and to precisely control its electronic structure.
An international team of scientists have unveiled the world's first production of a purified beam of neutron-rich, radioactive tantalum ions.
Scientists from Skoltech puzzled out the physical meaning of the mysterious Mendeleev Numbers and suggested calculating them based on the fundamental properties of atoms. They showed that both MNs and the chemical space built around them were more effective than empirical solutions proposed until then.
