A team at the University of Innsbruck, Austria has been successful in conducting electrons in metals along predetermined channels. This behaviour, observed for the first time in metals, provides important insights into the interactions of electrons - and on how the phenomenon of the current flow without any resistance loss, termed super-conductivity, can occur. Thereby this project aided by the Austrian Science Fund (FWF) combines fundamental research, at its best, with potential applications in the future.
High-temperature superconductors are ceramic materials that conduct electricity without resistance, and thus without loss, below a certain temperature. At higher temperatures, the behaviour rapidly changes and experiences resistance. Such discontinuous changes due to external influences are typical for the so-called "smart materials". Their discontinuous behaviour is closely linked with a mutual dependence of spatially confined electrons, giving rise to a commonly coordinated motion pattern. So far this dependence termed as correlation had been observed only in non-metals.

Quantum optical sensor for the first time tested in space – with a laser system from Berlin
23.01.2017 | Ferdinand-Braun-Institut Leibniz-Institut für Höchstfrequenztechnik
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
