Published Instrument adapted from astronomy observation helps capture singular quantum interference effects


By adapting technology used for gamma-ray astronomy, researchers has found X-ray transitions previously thought to have been unpolarized according to atomic physics, are in fact highly polarized.
Published Superconducting amplifiers offer high performance with lower power consumption


Researchers have devised a new concept of superconducting microwave low-noise amplifiers for use in radio wave detectors for radio astronomy observations, and successfully demonstrated a high-performance cooled amplifier with power consumption three orders of magnitude lower than that of conventional cooled semiconductor amplifiers. This result is expected to contribute to the realization of large-scale multi-element radio cameras and error-tolerant quantum computers, both of which require a large number of low-noise microwave amplifiers.
Published Sculpting quantum materials for the electronics of the future


The development of new information and communication technologies poses new challenges to scientists and industry. Designing new quantum materials -- whose exceptional properties stem from quantum physics -- is the most promising way to meet these challenges. An international team has designed a material in which the dynamics of electrons can be controlled by curving the fabric of space in which they evolve. These properties are of interest for next-generation electronic devices, including the optoelectronics of the future.
Published Qubits put new spin on magnetism: Boosting applications of quantum computers


Research using a quantum computer as the physical platform for quantum experiments has found a way to design and characterize tailor-made magnetic objects using quantum bits, or qubits. That opens up a new approach to develop new materials and robust quantum computing.
Published Breakthrough in the understanding of quantum turbulence


Researchers have shown how energy disappears in quantum turbulence, paving the way for a better understanding of turbulence in scales ranging from the microscopic to the planetary. The team's findings demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales. In the future, an improved understanding of turbulence beginning on the quantum level could allow for improved engineering in domains where the flow and behavior of fluids and gases like water and air is a key question. Understanding that in classical fluids will help scientists do things like improve the aerodynamics of vehicles, predict the weather with better accuracy, or control water flow in pipes. There is a huge number of potential real-world uses for understanding macroscopic turbulence.
Published Perovskite solar cells from the slot die coater -- a step towards industrial production


Solar cells made from metal halide perovskites achieve high efficiencies and their production from liquid inks requires only a small amount of energy. Scientists are investigating the production process. At the X-ray source BESSY II, the group has analyzed the optimal composition of precursor inks for the production of high-quality FAPbI3 perovskite thin films by slot-die coating. The solar cells produced with these inks were tested under real life conditions in the field for a year and scaled up to mini-module size.
Published Modelling superfast processes in organic solar cell material


In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.
Published Minimizing electric vehicles' impact on the grid


Some projections show that widespread adoption of electric vehicles might require costly new power plants to meet peak loads in the evening. A new study shows that placing EV charging stations strategic ways and setting up systems to initiate charging at delayed times could lessen or eliminate the need for new power plants.
Published Switching to hydrogen fuel could prolong the methane problem


Hydrogen is often heralded as the clean fuel of the future, but new research suggests that leaky hydrogen infrastructure could end up increasing atmospheric methane levels, which would cause decades-long climate consequences.

Scientists report the safe synthesis of hydrogen peroxide (H2O2), an oxidizing agent used in multiple industries including semiconductors, using a new rhodium-based catalyst. The catalyst is based on natural enzymes found in extremophile microorganisms, and the reaction meets three chemical ideals for H2O2 production: safe, use of a single vessel, and direct synthesis.
Published In the world's smallest ball game, scientists throw and catch single atoms using light


Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.
Published Hitting nuclei with light may create fluid primordial matter


A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.
