International research team uses topological platform to demonstrate coherent array of vertical lasers
FAU physicists control the flow of electron pulses through a nanostructure channel.
Physicists from the University of Regensburg publish results in the internationally renowned journal “Nature Communications”
A large international research collaboration led by Dr Kai-Qiang Lin and Professor John Lupton from the Institute of Experimental and Applied Physics at the University of Regensburg has been able to measure the effect of electrons with negative mass in novel semiconductor nanostructures. The international team includes scientists from Berkeley and Yale (USA), Cambridge (England) and Tsukuba (Japan).
Researchers from the Würzburg-Dresden Cluster of Excellence ct.qmat–Complexity and Topology in Quantum Matter – have conceived and realized a new quantum material: "Indenene". Consisting of a single layer of the chemical element Indium, indenene enriches the family of the so-called topological insulators. The triangular lattice behind its tailor-made materials-design concept is not only novel in the context of topological quantum materials but it also offers important advantages for future applications. Ever since the discovery of the first topological insulator this class of materials has been attributed enormous potential for the development of future electronics.
Using a sensor film to monitor how well aircraft and spacecraft withstand the mechanical stresses of flight: Würzburg researchers have received a prize for this idea, which comes with a lot of money.
A new type of atomic sensor made of boron nitride is presented by researchers in "Nature Communications". The sensor is based on a qubit in the crystal lattice and is superior to comparable sensors.
Researchers from the University of Augsburg and ETH Zurich have discovered giant conductivity of nanometre-sized domain walls separating polar regions in a non-oxide ferroelectric material. The high sensitivity of these walls to applied magnetic fields enables gigantic switching of the sample resistance, thus providing a route to new nanoelectronic building blocks. Such behaviour is unprecedented in non-oxides, which are less hampered by defects and deviations in composition than oxides.
A team of researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Liège and the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy have developed a microswimmer that appears to defy the laws of fluid dynamics: their model, consisting of two beads that are connected by a linear spring, is propelled by completely symmetrical oscillations. The Scallop theorem states that this cannot be achieved in fluid microsystems. The findings have now been published in the academic journal ‘Physical Review Letters’.
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell cultures. It may also prove successful against corona viruses.
The super-energetic jets that shoot out of black holes are in the focus of a new DFG research group. The researchers are being funded with 3.6 million euros.
