Im Focus: Bose-Einstein condensate: magnetic particles behave repulsively

Data transmission that works with magnetic waves instead of electric currents can be the basis for future information technologies. Some years ago, researchers at the University of Münster reached a new quantum state of magnetic particles at room temperature – a Bose-Einstein condensate. In a new study they show that the particles in the condensate behave repulsively, which leads to its stabilization. In this way, they resolve a long-standing contradiction between theory and practice. The study was published in the journal "Nature Communications".

Data transmission that works by means of magnetic waves instead of electric currents – for many scientists, this is the basis of future technologies that will...

Im Focus: Researchers watch the dynamics of plasmonic skyrmions made from light on ultra-smooth gold platelets for the first time

The destructive force of a tornado occurs due to the extremely high rotational speeds in its center, which is called “vortex”. Surprisingly, similar effects as in such storms are predicted for light that travels along an atomically smooth gold surface. This light can exhibit angular momentum and vortices. Researchers at the Universities of Stuttgart and Duisburg-Essen and the University of Melbourne (Australia) have now succeeded for the first time in filming these vortex patterns on the nanometer scale, which are named "skyrmions" after their discoverer Tony Skyrme. The journal Science reports this groundbreaking work in its issue of April 24, 2020.

When a figure skater starts to perform a pirouette and raises her arms, she turns around her own axis increasingly faster due to the conservation of angular...

Im Focus: Protective ventilation: computational lung model could significantly reduce the number of deaths from Covid-19 and ARDS

The use of mechanical ventilation can save lives – and not just for COVID-19 patients who develop severe respiratory problems. But at the same time, the ventilation pressure puts immense stress on delicate lung tissue. Especially for patients with preexisting lung damage, the use of ventilators can prove deadly. A computational lung model that’s been developed by the Technical University of Munich (TUM) can be used to reduce damage caused by mechanical ventilation – and could increase survival rates for patients significantly.

For patients suffering from acute lung failure (Acute Respiratory Distress Syndrome, ARDS), mechanical ventilation is a lifesaving treatment.

Im Focus: Quantum research unifies two ideas offering an alternative route to topological superconductivity

Researchers from University of Copenhagen have discovered a new way of developing topological superconductivity that may provide a useful route toward the use of Majorana zero modes as the foundation of qubits for quantum information.

Im Focus: Serendipity in the research field of magnetism

Scientists discover new light-matter interaction with which they can write nanometer-sized magnetic structures

A German-Chinese research team has discovered a new effect that for the first time enables the creation of extremely small magnetic structures, known as...

Im Focus: Scientists at TU Bergakademie Freiberg develop new ways of emergency ventilation

Scientists at TU Bergakademie Freiberg are currently testing a prototype of a pressure-controlled emergency ventilator. The device, which can be built with simple tools and is easy to maintain, could be used primarily in developing countries for the ventilation of emergency patients suffering from lung diseases.

To this end, the mine rescue team of TU Bergakademie Freiberg and the Institute for Machine Elements, Design and Production have combined their expertise.

Im Focus: The Lipid Code

New chemical tools can control the concentration of lipids in living cells

Lipids, or fats, have many functions in our body: They form membrane barriers, store energy or act as messengers, which regulate cell growth and hormone...

Im Focus: ESO telescope sees star dance around supermassive black hole, proves Einstein right

Observations made with ESO's Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein's general theory of relativity. Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton's theory of gravity. This long-sought-after result was made possible by increasingly precise measurements over nearly 30 years, which have enabled scientists to unlock the mysteries of the behemoth lurking at the heart of our galaxy.

"Einstein's General Relativity predicts that bound orbits of one object around another are not closed, as in Newtonian Gravity, but precess forwards in the...

Im Focus: Particle billiards with three players

Frankfurt researchers solve puzzle of Compton scattering – new approach for testing theories in quantum mechanics

Light can be used to knock electrons out of atoms, with light particles and electrons bouncing off each other like two billiard balls – Compton scattering. Why...

Im Focus: New method for the temperature-dependent generation of terahertz radiation

Physicists from the universities of Augsburg and Münster have presented a new type of emitter for generating terahertz radiation, which can be switched on or off by varying the temperature. In the future, it could possibly enable the construction of higher intensity radiation sources. There is great interest in such emitters: terahertz radiation can be used, for example, to make defects in materials visible, to detect weapons under clothing or to detect skin cancer cells. The study was published in the journal "Applied Physics Letters".

Terahertz rays are electromagnetic waves, just like radio waves or light. What differentiates them is the frequency with which they oscillate: one hundred...
