Using machine learning methods, researchers at TU Graz can predict the structure formation of functionalized molecules at the interfaces of hybrid materials. Now they have also succeeded in looking behind the driving forces of this structure formation.
A Clemson University physicist and collaborators from China and Denmark have created a new and potentially paradigm-shifting high-performance thermoelectric compound.
Hafnium-based thin films, with a thickness of only a few nanometres, show an unconventional form of ferroelectricity. This allows the construction of nanometre-sized memories or logic devices. However, it was not clear how ferroelectricity could occur at this scale. A study that was led by scientists from the University of Groningen showed how atoms move in a hafnium-based capacitor: migrating oxygen atoms (or vacancies) are responsible for the observed switching and storage of charge.
An international team of physicists has identified a new technique for testing the quality of quantum correlations. Quantum computers run their algorithms on large quantum systems by creating quantum correlations across all of them. It is important to verify the quantum correlations achieved are of the desired quality. However, carrying out checks is resource-intensive so the team has proposed a new technique that significantly reduces the number of measurements while increasing the resilience against noise.
A team of scientists from Germany has managed to successfully perform atom interferometry in space for the first time - on board a sounding rocket.
A simple yet elegant change to code studied for more than 20 years could shorten timeline to achieve scalable quantum computation and has attracted the attention of quantum computing programs at Amazon Web Services and Yale University.
Researchers have used a technique similar to MRI to follow the movement of individual atoms in real time as they cluster together to form two-dimensional materials, which are a single atomic layer thick.
The long-awaited first results from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists' best theory, the Standard Model of particle physics.
Most materials go from being solids to liquids when they are heated. One rare counter-example is helium-3, which can solidify upon heating. This counterintuitive and exotic effect, known as the Pomeranchuk effect, may now have found its electronic analogue in a material known as magic-angle graphene, says a team of researchers from the Weizmann Institute of Science led by Prof. Shahal Ilani, in collaboration with Prof. Pablo Jarillo-Herrero's group at the Massachusetts Institute of Technology (MIT).
A new estimation of the strength of the magnetic field around the muon--a sub-atomic particle similar to, but heavier than, an electron--closes the gap between theory and experimental measurements, bringing it in line with the standard model that has guided particle physics for decades.
