Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be. Lots of astronomical bodies in the Universe have magnetic fields, whether…
Project 8 marks a major milestone in its quest to measure neutrino mass. The humble neutrino, an elusive subatomic particle that passes effortlessly through normal matter, plays an outsized role among the particles that comprise our universe. To fully explain how our universe came to be, we need to know its mass. But, like so many of us, it avoids being weighed. Now, an international team of researchers from the United States and Germany leading an ambitious quest called Project…
ERC Starting Grant for Daniel Keefer. Whether solar cells or photosynthesis in plants: The interaction of light with molecules often plays a crucial role in chemical and physical processes. In many cases, however, the exact quantum mechanical processes are not sufficiently understood. It is difficult to investigate them experimentally, because some signals emitted by the molecules are hidden by signals that are superimposed on them. Daniel Keefer, group leader at the Max Planck Institute for Polymer Research, has now obtained…
… begins its transfer to the US for the scheduled 2024 launch. To observe the space environment landing on the low-latitude Reiner Gamma region on the near side of the Moon. The Ministry of Science and ICT (Minister Jong-Ho Lee, hereinafter referred to as ‘MSIT’) and the Korea Astronomy and Space Science Institute (Director Young-Deuk Park, hereinafter referred to as ‘KASI’) announced the beginning of the transfer of the lunar space environment monitor, ‘LUSEM'(Lunar Space Environment Monitor) that will be…
Stampede2 simulations help capture helium gas clouds escaping distant planet. A planet about 950 light years from Earth could be the Looney Tunes’ Yosemite Sam equivalent of planets, blowing its atmospheric ‘top’ in spectacular fashion. The planet called HAT-P-32b is losing so much of its atmospheric helium that the trailing gas tails are among the largest structures yet known of an exoplanet, a planet outside our solar system, according to observations by astronomers. Three-dimensional (3D) simulations on the Stampede2 supercomputer of the Texas Advanced Computing Center…
Auburn scientists receive a Department of Energy award to accelerate fusion energy research by developing a Findable, Interoperable, Accessible, and Reusable (FAIR) data platform and training a diverse workforce. Fusion is the process of combining two light atomic nuclei to form a single heavier one while releasing massive amounts of energy. The Sun and all stars are powered through fusion, which makes it the universe’s preferred method of producing energy. Recent breakthroughs in fusion research have led to the US…
Quantum random number generation based on a perovskite light emitting diode. Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption developed at Linköping University, Sweden. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication. In an increasingly connected world, cybersecurity is becoming increasingly important to protect not just the individual, but also, for example,…
Higher-order topological insulators are unusual materials that can support topologically protected states. Recently discovered disclination states also belong to the class of higher-order topological states but are bound to the boundary of the disclination defect of the higher-order topological insulator and can be predicted using the bulk-disclination correspondence principle. So far, topological disclination states were observed only in the linear regime, while the interplay between nonlinearity and topology in the systems with disclinations has never been studied experimentally. In a…
Researchers at Mainz University, TU Darmstadt, and Wuhan University overcome fundamental obstacles for writing and drawing lines, letters, and complex patterns within the bulk of a liquid. Writing is an age-old cultural technique. Thousands of years ago, humans were already carving signs and symbols into stone slabs. Scripts have become far more sophisticated since then but one aspect remains the same: Whether the writer is using cuneiform or a modern alphabet, a solid substrate, such as clay or paper, is…
Quantum physics has allowed for the creation of sensors far surpassing the precision of classical devices. Now, several studies in Nature show that the precision of these quantum sensors can be significantly improved using entanglement produced by finite-range interactions. Innsbruck researchers led by Christian Roos were able to demonstrate this enhancement using entangled ion-chains with up to 51 particles. Metrological institutions around the world administer our time, using atomic clocks based on the natural oscillations of atoms. These clocks, pivotal…
Experiments promote a curious flipside of decaying monopoles: a reality where particle physics is quite literally turned on its head. The field of quantum physics is rife with paths leading to tantalising new areas of study, but one rabbit hole offers a unique vantage point into a world where particles behave differently—through the proverbial looking glass. Dubbed the ‘Alice ring’ after Lewis Carroll’s world-renowned stories on Alice’s Adventures in Wonderland, the appearance of this object verifies a decades-old theory on…
A flexible, language-based approach proves surprisingly effective at solving intractable problems in materials science. With their intricate arrangements and dynamic functionalities, proteins perform a plethora of biological tasks by employing unique arrangements of simple building blocks where geometry is key. Translating this nearly limitless library of arrangements into their respective functions could let researchers design custom proteins for specific uses. In Journal of Applied Physics, from AIP Publishing, Markus Buehler of the Massachusetts Institute of Technology combined attention neural networks,…
Remote-sensing data will complement Juno spacecraft’s in situ observations. The Space Telescope Science Institute recently awarded Southwest Research Institute a large project to use the Hubble and James Webb telescopes to remotely study Io, the most volcanically active body in the solar system. The study will complement the upcoming flybys of the Jupiter moon by NASA’s Juno spacecraft and will provide insights into Io’s contributions to the plasma environment around Jupiter. Large Hubble projects request 75 orbits or more; this…
National University of Singapore (NUS) physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next generation moiré quantum matter. Moiré patterns are formed when two identical periodic structures are overlaid with a relative twist angle between them or two different periodic structures but overlaid with or without twist angle. The twist angle is the angle between the crystallographic orientations of the two…
New experimental research for the first time measures the speed of molecular charge migration. To discover how light interacts with molecules, the first step is to follow electron dynamics, which evolve at the attosecond timescale. The dynamics of this first step have been called charge migration (CM). CM plays a fundamental role in chemical reactions and biological functions associated with light–matter interaction. For years, visualizing CM at the natural timescale of electrons has been a formidable challenge in ultrafast science…
A powerful satellite called XRISM (X-ray Imaging and Spectroscopy Mission) is set to provide astronomers with a revolutionary look at the X-ray sky. XRISM, led by JAXA (Japan Aerospace Exploration Agency) in collaboration with NASA and with contributions from ESA (European Space Agency), is scheduled to launch on an H-IIA rocket from Japan’s Tanegashima Space Center at 8:26 p.m. EDT on Sunday, Aug. 27 (9:26 a.m. on Monday, Aug. 28, in Japan). JAXA will stream the launch live on YouTube, with a broadcast in both English and Japanese starting at 7:55 p.m. EDT….
