Generating stable qubits at room temperature

A group of researchers reports that they have achieved quantum coherence at room temperature, which is the ability of a quantum system to maintain a well-defined state over time without getting affected by surrounding disturbances …read more […]

Astronomers spot an Earth-sized planet with a ‘lava hemisphere’

In a system with two known planets, astronomers spotted something new: A small object transiting across the sun-sized star. This turned out to be another planet, which was extra hot and Earth-sized. …read more […]

Thin film reveals origins of pre-superconducting phase

RIKEN physicists have found an ideal platform for exploring the behavior of electrons in a material as it approaches superconductivity. This could help to develop new superconductors that operate at more convenient temperatures than existing ones. The study is published in the journal Physical Review B. …read more […]

First direct imaging of tiny noble gas clusters at room temperature

For the first time, a research team has succeeded in stabilizing and directly imaging small clusters of noble gas atoms at room temperature. This achievement opens exciting possibilities for condensed matter physics and applications in quantum information technology. …read more […]

Tidal disruption events and what they can reveal about black holes and stars in distant galaxies

At the center of most large galaxies lives a supermassive black hole (SMBH). The Milky Way has Sagittarius A*, a mostly dormant SMBH whose mass is around 4.3 million times that of the sun. But if you look deeper into the universe, there are vastly larger SMBHs with masses that can reach up to tens of billions of times the mass of our sun. …read more […]

The first 3D map of magnetic fields in our galaxy explains star-forming regions

A team of astronomers including those from the University of Tokyo have created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms of our galaxy break away from this general picture significantly and are tilted away from the galactic average by a high degree. …read more […]

Potential solvents identified for building on the moon and Mars

Researchers have taken the first steps toward finding liquid solvents that may someday help extract critical building materials from lunar- and Martian-rock dust, an important part of making long-term space travel possible. …read more […]

A three-step mechanism explaining ultraviolet-induced CO desorption from CO ice

The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, the molecular mechanisms underpinning it are yet to be fully uncovered. …read more […]

Exciplex route to white organic light emitting diodes: The role of a spacer layer

Organic light emitting diodes (OLEDs) have matured to commercial level. Yet, their widespread market adoption is hindered due to high costs and complicated device architecture. Researchers are actively exploring innovative device engineering strategies to circumvent these issues. …read more […]

Astronomers make rare exoplanet discovery, and a giant leap in detecting Earth-like bodies

Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion—shedding light on the formation of planets like Earth. …read more […]

Research offers insights into the metal-to-insulator transition without breaking symmetry

Metal-to-insulator transition—a process that turns materials from a conductor to an insulator—has been a crucial process behind microelectronic switches, nonvolatile memory, and neuromorphic computing materials. In many cases, this transition is accompanied by drastic changes in the electronic or structural symmetry of the material, which can bring about other unintended property changes to the material. It is therefore desired to realize such a transition without breaking the symmetry of the materials. …read more […]

Ultra-short laser flashes on demand: Controllable light pulse pairs from a single-fiber laser

In an innovative approach to controlling ultrashort laser flashes, researchers from the Universities of Bayreuth and Konstanz are using soliton physics and two pulse combs within a single laser. The method has the potential to drastically speed up and simplify laser applications. …read more […]

Researchers use spinning metasurfaces to craft compact thermal imaging system

Researchers have developed a new technology that uses meta-optical devices to perform thermal imaging. The approach provides richer information about imaged objects, which could broaden the use of thermal imaging in fields such as autonomous navigation, security, thermography, medical imaging and remote sensing. …read more […]

Astronomers find direct link that supernovae give rise to black holes or neutron stars

Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the universe—black holes and neutron stars. With the help of the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and ESO’s New Technology Telescope (NTT), two teams were able to observe the aftermath of a supernova explosion in a nearby galaxy, finding evidence for the mysterious compact object it left behind. …read more […]

Jupiter has at least three magnetosheath jets, finds Voyager 2 data study

A team of astrophysicists and astronomers from Harbin Institute of Technology, Johns Hopkins University and Peking University has found evidence from Voyager 2 data showing that Jupiter has at least three magnetosheath jets. The study is published in Nature Communications. …read more […]
