The team lead by Stefan Foelsch used copper (Cu) and cobalt (Co) atoms to produce pairs or various chains of atoms on a substrate surface made of crystalline copper. The scientists report on their work in Physical Review Letters (J. Lagoute et al.: „Doping of monatomic Cu chains with single Co atoms“, published online on April 6).
“We manipulated the atoms in a low-temperature scanning tunneling microscope”, says Stefan Foelsch. He adds: “We found that the quantum effects in these structures can be understood within the framework of textbook physics describing the electronic properties of simple molecules.” Thus, it is possible to taylor “artificial molecules” supported by a solid surface made of magnetic and non-magnetic elements.
The nanostructures engineered and characterized constitute a promising model case for future investigations in order to gain insight into the magnetism of ultimately small structures. Stefan Foelsch says that this is an issue of utmost technological relevance.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
