Pairing of electrons in artificial atoms discovered
Researchers from the Department of Physics at Universität Hamburg, observed a quantum state that was theoretically predicted more than 50 years ago by Japanese theoreticians but so far eluded detection. By tailoring an artificial atom on the surface of a superconductor, the researchers succeeded in pairing the electrons of the so-called quantum dot, thereby inducing the smallest possible version of a superconductor.

A new type of quantum bit in semiconductor nanostructures
Researchers have created a quantum superposition state in a semiconductor nanostructure that might serve as a basis for quantum computing. The trick: two optical laser pulses that act as a single terahertz laser pulse. A German-Chinese research team has successfully created a quantum bit in a semiconductor nanostructure.

High-performance digital system for the design of customized polymers
It is impossible to imagine everyday life without polymers. However, they represent only a small section of the huge number of polymers that could theoretically exist. Christopher Kuenneth at the University of Bayreuth, Germany, together with research partners in Atlanta, USA, has now developed a digital system that promises extraordinarily high economic, technological and ecological benefits: From around 100 million theoretically possible polymers, it can filter out at unprecedented speed precisely those materials that are most suitable for targeted applications.

Fabrication of drop-etched quantum dots that glow in the optical C-band.
Researchers from the Department of Physics and the Institute for Photonic Quantum Systems (PhoQS) in Paderborn have successfully produced quantum dots - nanoscopic structures in which the quantum properties of matter come into play - that glow in the optical C-band at a wavelength between 1530 and 1565 nanometers as part of a project funded within the Collaborative Research Center/TRR 142.

Aluminium-ion batteries with improved storage capacity
Research team develops organic redox polymer as positive electrode material for aluminium-ion batteries Aluminium-ion batteries are seen as a promising alternative to conventional batteries that use scarce and difficult-to-recycle raw materials such as lithium. This is because aluminium is one of the most common elements in the Earth's crust, is easier to recycle, and is also safer and less expensive than lithium.

Let information flow faster - with light instead of electricity
Either 1 or 0. Either current flows or it does not. In electronics, everything is controlled via the binary system. Electrons already generate information quite fast and well, pass them on and take over various switching functions. But it can be done even faster. Paul Herrmann and Sebastian Klimmer from the Friedrich Schiller University of Jena have proven that.

ToCoTronics Extended
The Collaborative Research Centre ToCoTronics in condensed matter physics will be extended for four more years. The German Research Foundation is funding it with 12 million euros. Topological materials are intensively investigated in the world. This boom started at Julius-Maximilians-Universität (JMU) Würzburg, where the physics professor Laurens Molenkamp realized the first topological insulator in 2007.

Specially coated titanium reduces risk of clots on prostheses
Around 25,000 artificial heart valves are implanted in Germany per year because the original heart valve is damaged, for example, by an infection. The mechanical heart valves are made of titanium dioxide, among other materials, and last for many years. However, because blood tends to clot on contact with these material surfaces, there is a risk of blood clots forming on the surface of mechanical heart valves.

New glass from the computer
Glass is a very special material: it can be produced in almost unlimited variety from compounds of almost all elements of the periodic table. The only prerequisite is that the components can be melted together and that the melt is then cooled quickly enough. In the process, the liquid mixture solidifies and forms a glass.

More power from waste heat
When fossil fuels, but also biofuels, are burned, large amounts of the energy are lost as waste heat. Thermoelectric materials could convert this heat into electricity, but they are not yet efficient enough for technical application. A team from the Max Planck Institut für Eisenforschung has now increased the efficiency of a thermoelectric material by elucidating the influence of the microstructure on the material and optimizing the material's properties by adding titanium.

Researchers study water-based battery recycling
Millions in funding for collaborative project: focus on sustainability and circular economy The recycling of lithium-ion batteries is playing an increasingly important role in battery research not only because of its environmental sustainability, but also because of the shortage of raw materials. While the number of production facilities is increasing in Germany and Europe, there is a lack of natural deposits of numerous starting materials for battery cell production.

An important step towards the quantum internet
The cornerstone for 1000-fold improvement in communication rates for bridging long distances. Diamond is of great importance for future technologies such as the quantum internet. Special defect centers can be used as quantum bits (qubits) and emit single photons. To enable data transmission with practicable communication rates over long distances in the quantum network, all photons must be collected in optical fibers and transmitted without being lost.
