Energy-efficient spin current can be controlled by magnetic field and temperature

“SCMR effect simplifies the design of fundamental spintronic components The transition from light bulbs to LEDs has drastically cut the amount of electricity we use for lighting. Most of the electricity consumed by incandescent bulbs was, after all, dissipated as …

Scientists develop highly sensitive molecular optical pressure sensor

“Optical pressure measurements possible in solid state and in solution / Molecular ruby for use in materials sciences or catalysis Chemists at Johannes Gutenberg University Mainz (JGU) and at the Université de Montréal in Canada have developed a molecular system capable …

Laser spectroscopy measurements reveal size and shape of the nucleus of nobelium

“Precise measurement of the optical excitation of atomic levels in the atomic shell of three isotopes of the heavy element 102 Sizes and shapes of nuclei with more than 100 protons were so far experimentally inaccessible. Laser spectroscopy is an …

Mysterious IceCube event may be caused by a tau neutrino

“Theoretical physicists calculate the origin of a high-energy particle track captured by the IceCube Neutrino Observatory It was just eight years ago that the IceCube detector, a research center located at the South Pole to detect neutrinos emanating from the …

Cosmic x-rays may provide clues to the nature of dark matter

“Physicists propose a new theory of dark matter based on the detection of unusual x-ray radiation from galaxies Dark matter is increasingly puzzling. Around the world, physicists have been trying for decades to determine the nature of these matter particles …

Ultralight axions are unlikely to be candidates for dark matter

“Astrophysical and cosmological observations indicate that most of our universe is invisible, composed of dark matter and dark energy. Only about five percent of what is out there is visible to us, such as matter here on Earth or in …

Quantum computing on the move

“A future quantum computer, using “quantum bits” or qubits, might be able to solve problems which are not tractable for classical computers. Scientists are currently struggling to build devices with more than a few qubits, with the challenge arising that …

Imaging how magnetism goes surfing

“Researchers use advanced dynamic imaging to visualise deformation (sound) waves in crystals Using advanced dynamic imaging, researchers have been able to visualise deformation (sound) waves in crystals and measured the effect on nanomagnetic elements. This offers new low power magnetization …
