Experiment Reveals Clear Distinction Between Two Different States of Skyrmion Phase

In manganese monosilicide (MnSi), microscopic magnetic vortices - skyrmions - may behave as "collectivists" or "individuals", i.e. they are able to create a single structure, or they can also split up individually.

Researchers Show How Protons Inside Ice Behave

While drinking your favourite cold drink, you probably do not imagine what is going on inside each ice cube. At the Okinawa Institute of Science and Technology Graduate University (OIST), the Theory of Quantum Matter Unit, led by Professor Nic Shannon has explained in detail the theory behind two experiments that show how protons inside ice behave. Their findings have been published in Physical Review B.

Breakthrough Method to Measure Strength of Coherence of Superposition in Quantum States

UAB researchers have come up with a method that allows measuring the strength of the coherence of superposition in any given quantum state, similar to the famous Schrödinger's cat, which was simultaneously dead and alive. For the first time ever, the method can be used in any given quantum state in superposition.

International Research Group Elucidates Dynamics of Quantum Spin Orbital Liquid

An international research group observed a state in copper oxides in which orbital degrees of freedom did not freeze at low temperatures and electrons fluctuated due to quantum fluctuations. The group also clarified the time scale of these quantum fluctuations in multifrequency electron spin resonance (ESR) experiments in a strong magnetic field for the first time.

Researchers Discover White Dwarf Star with Oxygen-Dominated Atmosphere

Researchers have discovered a white dwarf star with an atmosphere dominated by oxygen, a type of white dwarf that has been theorized to exist but not identified to date.

NASA's Hubble Space Telescope Peers Deep into Heart of Milky Way Galaxy

Peering deep into the heart of our Milky Way galaxy, NASA's Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Except for a few blue foreground stars, the stars are part of the Milky Way's nuclear star cluster, the most massive and densest star cluster in our galaxy. So packed with stars, it is equivalent to having a million suns crammed between us and our closest stellar neighbor, Alpha Centauri. At the very hub of our galaxy, this star cluster surrounds the Milky Way's central supermassive black hole, which is about 4 million times the mass of our sun.

Study Provides New Insights into Electronic Characteristics of High-Temperature Superconductors

Superconducting materials have the characteristic of letting an electric current flow without resistance. The study of superconductors with a high critical temperature discovered in the 1980s remains a very attractive research subject for physicists. Indeed, many experimental observations still lack an adequate theoretical description.

New ALMA Image Shows Finest Details of Planet-Forming Disc Around Sun-like Star

This new image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows the finest detail ever seen in the planet-forming disc around the nearby Sun-like star TW Hydrae. It reveals a tantalising gap at the same distance from the star as the Earth is from the Sun, which may mean that an infant version of our home planet, or possibly a more massive super-Earth, is beginning to form there.

Scientists Measure Motion and Velocity of Unruly Atoms Using X-rays

X-rays have long been used to make pictures of tiny objects, even single atoms. Now a team of scientists has discovered a new use for X-rays at the atomic scale: using them like a radar gun to measure the motion and velocity of complex and messy groups of atoms.

SETI Institute Inaugurates New Red Dwarf Survey

The SETI Institute has inaugurated a greatly expanded hunt for deliberately produced radio signals that would indicate the presence of extraterrestrial intelligence. Over the course of the next two years, it will scrutinize the vicinities of 20,000 so-called red dwarf stars.
