New Method Measures Characteristic Microwaves to Read Out Orientation of Magnetic Vortices in Nanodisks

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Forschungszentrum Jülich (FZJ) together with a colleague at the French Centre National de la Recherche Scientifique (CNRS) in Strasbourg have found a new way to electrically read out the orientation of magnetic vortices in nanodisks. Their new method relies on measuring characteristic microwaves emanating from the vortices.

Physicists Successfully Characterize Electromagnetic Properties of Skyrmion-Materials

Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, a team of physicists succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and developed a unified theoretical description of their behavior. This lays the foundation for future electronic components with purpose-designed properties.

Study Contributes to Determination of Nature of Dark Matter

Recent research conducted by scientists from the University of Granada can contribute to determine the nature of dark matter, one of the most important mysteries in physics. As indirect evidence provided by its gravitational effects, dark matter amounts to more than 80% of the universe.

Coursera to Begin Fourth Edition of “Exploring Quantum Physics” MOOC

“Exploring Quantum Physics" (EQP) a massive open online course (MOOC) on Coursera, begins its fourth edition on March 30, 2015. The link is: https://www.coursera.org/course/eqp. Taught by JQI Fellows Victor Galitski and Charles Clark, the course materials are linked to Galitski's 2013 Oxford University Press book, Exploring Quantum Mechanics. Some 84,000 students have enrolled in the first three editions of EQP, which were presented in 2013 and 2014.

Oddly Small, Far-Flung, Out of Place Group of Stars

Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way's "suburbs." It is located where astronomers have never spotted such a small cluster of stars before.

Astronomers Discover Dust-Filled Galaxy from the Very Early Universe

Dust plays an extremely important role in the universe - both in the formation of planets and new stars. But dust was not there from the beginning and the earliest galaxies had no dust, only gas. Now an international team of astronomers, led by researchers from the Niels Bohr Institute, has discovered a dust-filled galaxy from the very early universe.

Public Lecture on the Milky Way and Structure of the Cosmic Web

The Milky Way, the galaxy that contains our solar system, is located in a remarkable place, lying at the center of a thin plane of galaxies forming a wall between two vast regions devoid of galaxies.

Amazingly Dusty Galaxy May Have Been in a Rush to Create Stars

A team of astronomers, led by Darach Watson, from the University of Copenhagen used the Very Large Telescope's X-shooter instrument along with the Atacama Large Millimeter/submillimeter Array to observe one of the youngest and most remote galaxies ever found.

Scientists Directly Film Quantum Mechanics and its Paradoxical Nature

Quantum mechanics tells us that light can behave simultaneously as a particle or a wave. However, there has never been an experiment able to capture both natures of light at the same time; the closest we have come is seeing either wave or particle, but always at different times.

Iron Vapor was Generated When Growing Earth Collided with Other Solar System Objects

Violent collisions between the growing Earth and other objects in the solar system generated significant amounts of iron vapor, according to a new study by LLNL scientist Richard Kraus and colleagues.

HITS Astrophysicist Appointed Professor for Theoretical Astrophysics at Heidelberg University

Modern astronomy began with a supernova. In November 1572, Danish astronomer Tycho Brahe discovered a new star – and destroyed the idea of a sky of fixed stars. Today, we know that Brahe was observing the death of a star, which ended in a massive explosion. Friedrich Röpke aims to find out how these supernova explosions proceed.
