6G mobile communications is expected to pave the way for innovative applications such as Artificial Intelligence, Virtual Reality and Internet of Things in everyday life from 2030. This will require a much higher performance capability than that of the current 5G mobile standard, involving new hardware solutions. At EuMW 2022, Fraunhofer IAF will therefore present an energy-efficient GaN-based transmitter module for the 6G-relevant frequency ranges above 70 GHz, which was developed jointly with Fraunhofer HHI. The high performance of the…

New production technology opens the way to quantum light sources with fiber optic compatibility. Across the world, specialists are working on implementing quantum information technologies. One important path involves light: Looking ahead, single light packages, also known as light quanta or photons, could transmit data that is both coded and effectively tap proof. To this end, new photon sources are required that emit single light quanta in a controlled fashion – and on demand. Only recently has it been discovered…

In classical models of stellar evolution, so far little importance has been attached to the early evolution of stars. Thomas Steindl from the Institute of Astro- and Particle Physics at the University of Innsbruck now shows for the first time that the biography of stars is indeed shaped by their early stage. The study was published in Nature Communications. In classical models of stellar evolution, so far little importance has been attached to the early evolution of stars. Thomas Steindl…

From The City College of New York’s Center for Discovery and Innovation and the Physics Department comes news of a new type of magnetic quasiparticle created by coupling light to a stack of ultrathin two-dimensional magnets. This achievement sprouting from a collaboration with the University of Texas at Austin lays the foundation for an emergent strategy to artificially design materials by ensuring their strong interaction with light. “Implementing our approach with magnetic materials is a promising path towards efficient magneto-optical effects,” said…

Titanium shows superconductivity above 26K at high pressures. Element superconductors are important either for superconducting mechanism studies or for potential applications because of the single composition. However element superconductor (SC) usually show very low transition temperature (Tc) typically below 10K. Recently Prof. Changqing Jin’s team at IOPCAS discovered Ti metal to be superconductive with Tc above 26K at high pressures: the record high for element superconductors so far. They found that Ti metal keeps superconductive with Tc above 20 K…

Whether looking out into space or peering deep into the microscopic realm, there is always more to see. In the case of solids, there is a world of atoms and particles teeming with activity that ultimately leads to useful properties like electrical conduction, magnetism, and insulation. One of the most powerful tools for seeing the unseen is a scanning tunneling microscope or STM for short. Rather than an optical lens, its powerful eye comes from an electrical current that passes…

UC Santa Barbara researchers create a device to streamline interactions between ultra-cold and room-temperature computers. Many state-of-the-art technologies work at incredibly low temperatures. Superconducting microprocessors and quantum computers promise to revolutionize computation, but scientists need to keep them just above absolute zero (-459.67° Fahrenheit) to protect their delicate states. Still, ultra-cold components have to interface with room temperature systems, providing both a challenge and an opportunity for engineers. An international team of scientists, led by UC Santa Barbara’s Paolo Pintus, has…

Combining synthesis, characterization, and theory confirmed the exotic properties and structure of a new intrinsic ferromagnetic topological material. The Science Topological insulators act as electrical insulators on the inside but conduct electricity along their surfaces. Researchers study some of these insulators’ exotic behavior using an external magnetic field to force the ion spins within a topological insulator to be parallel to each other. This process is known as breaking time-reversal symmetry. Now, a research team has created an intrinsic ferromagnetic…

Isotope-controlled silicon carbide for solid-state quantum devices. Fraunhofer IISB develops solid-state quantum electronics based on silicon carbide (SiC). The basis are SiC layers with precisely defined isotope concentrations epitaxially grown on SiC wafers. Defined point defects (color centers) generated in isotope-controlled SiC enable a variety of quantum devices. SiC-based solid-state devices offer enormous potential for the broad introduction of quantum technologies. At Fraunhofer IISB, a research group is developing optimized base materials and process technologies for solid-state quantum electronics using…

… a breakthrough in revealing the origin of life. The long-held dream of chemists to observe the structural dynamics of a single molecule have been now made possible. Single molecules sized about 1 nanometer (nm, 1 billionth of a meter) exist in a volatile state under ambient conditions. Considering that the Coronavirus, which is about 100 nm in size, spreads rapidly in the air shows how difficult it is to observe a single molecule. Recently, a Korean research team has…

The MICROSCOPE mission has confirmed the ‘equivalence principle’ with unprecedented accuracy, bolstering Einstein’s general relativity. The result, announced this week by a team led by the French space agency CNES, is a triumph for Einstein’s general relativity. However, it also potentially rules out some candidate universal theories of physics. General relativity is the best theory of gravity – positing that instead of being a ‘pulling’ force, the action of gravity is caused by large bodies like planets bending spacetime, curving…

Properties of heaviest element studied so far measured at GSI/FAIR. An international research team has succeeded in gaining new insights into the chemical properties of the superheavy element flerovium — element 114 — at the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The measurements show that flerovium is the most volatile metal in the periodic table. Flerovium is thus the heaviest element in the periodic table that has been chemically studied. With the results, published in the…

Strong alternating magnetic fields can be used to generate a new type of spin wave that was previously just theoretically predicted. This was achieved for the first time by a team of physicists from Martin Luther University Halle-Wittenberg (MLU). They report on their work in the scientific journal “Nature Communications” and provide the first microscopic images of these spin waves. The basic idea of spintronics is to use a special property of electrons – spin – for various electronic applications…

New physics discovered where crystal patterns match weave of traditional baskets. Physicists have discovered a material in which atoms are arranged in a way that so frustrates the movement of electrons that they engage in a collective dance where their electronic and magnetic natures appear to both compete and cooperate in unexpected ways. Led by Rice University physicists, the research was published online today in Nature. In experiments at Rice, Oak Ridge National Laboratory (ORNL), SLAC National Accelerator Laboratory, Lawrence…

A weak proton emission following beta decay constrains the formation of elements in stellar nova explosions and determines their peak temperature. The Science Energy released by nuclear reactions drives exploding stars such as novae. To simulate novae accurately on computers, researchers need accurate inputs for the rates of nuclear reaction. The unknown rates of some nuclear reactions dramatically influence nova simulations. Nuclear physicists have now determined an important and challenging proton-capture reaction rate. Proton capture involves the collision of an…
