“In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively …
“Extremely intense light pulses generated by free-electron lasers (FELs) are versatile tools in research. Particularly in the X-ray range, they can be deployed to analyze the details of atomic structures of a wide variety of materials and to follow fundamental …
“Two-dimensional (2D) materials possess extraordinary properties. They usually consist of atomic layers that are only a few nanometers thick and are particularly good at conducting heat and electricity, for instance. To the astonishment of many scientists, it recently became known …
“Nanowires under tension create the basis for ultrafast transistors Smaller chips, faster computers, less energy consumption. Novel concepts based on semiconductor nanowires are expected to make transistors in microelectronic circuits better and more efficient. Electron mobility plays a key role …
“Pulsed electric fields, such as the ones caused by lightning strikes, manifest themselves as voltage spikes, posing a destructive threat to electronic components and causing considerable damage. Scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have now discovered that such voltage spikes …
“Liquid-metal experiment provides insight into the heating mechanism of the Sun’s corona Why the Sun’s corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A “hot” trail to explain this …
“Acoustic manipulation of electron spins could lead to new methods of quantum control Color centers are lattice defects in crystals that can capture one or more additional electrons. The spin of these electrons is very sensitive to external electric and …
“New study elucidates fundamental enigma of topological insulators They are regarded as one of the most interesting materials for future electronics: Topological insulators conduct electricity in a special way and hold the promise of novel circuits and faster mobile communications …
“Climate protection means increasingly turning to renewable energies. But in order to store the energy produced by solar, wind and other regenerative processes, sophisticated systems are required. Today’s storage options are still too expensive and hardly or even impossible …
“Research team develops new method to study astrophysical processes in the laboratory In the depths of space, there are celestial bodies where extreme conditions prevail: Rapidly rotating neutron stars generate super-strong magnetic fields. And black holes, with their enormous gravitational …
