Physicists from the University of Konstanz explore superconductivity for information processing.

There is often a pronounced symmetry when you look at the lattice of crystals: the atoms are uniformly arranged. This behavior was also to be expected by a crystal, which physicists from Germany and Poland produced: a compound from an indium arsenide semiconductor, spiked with some iron. The material, however, did not adhere to perfect symmetry. The iron formed two-dimensional, lamellar-shaped structures in the crystal that lent the material a striking property: it became magnetic.

A team at the HZB has improved the manufacturing process of photocathodes and can now provide photocathodes with high quantum efficiency for bERLinPro.

Research teams from UNSW are investigating multiple pathways to scale up atom-based computing architectures using spin-orbit coupling -- advancing towards their goal of building a silicon-based quantum computer in Australia.

A new study published in the journal Science, could provide engineers new design rules for creating microelectronics, membranes, and tissues, and open up better production methods for new materials. At the same time, the research helps uphold a scientific theory that has remained unproven for over a century.

In the drive to find new ways to extend electronics beyond the use of silicon, physicists are experimenting with other properties of electrons, beyond charge. In work published today (Dec 7) in the journal Science, a team led by Penn State professor of physics Jun Zhu describes a way to manipulate electrons based on their energy in relation to momentum -- called 'valley degree of freedom.'

The same fluoride in your toothpaste might soon compete with lithium for longer-lasting batteries.

Scientists mapping out the quantum characteristics of superconductors -- materials that conduct electricity with no energy loss -- have entered a new regime. Using newly connected tools named OASIS at Brookhaven Lab, they've uncovered previously inaccessible details of the 'phase diagram' of one of the most commonly studied 'high-temperature' superconductors.
