A three-dimensional phase diagram of heavy-fermion compound with competing quantum phases

URu2Si2 is a metal that belongs to the family of heavy-fermion compounds in which several quantum phases (e.g., magnetism and superconductivity) can compete or coexist. These metals exhibit small energy scales that are easy to tune, a characteristic that makes them ideal for testing new physical ideas and concepts.

Researchers observe branched flow of light for the first time

A team of researchers from the Technion – Israel Institute of Technology has observed branched flow of light for the very first time. The findings are published in Nature and are featured on the cover of the July 2, 2020 issue.

Thermophones offer new route to radically simplify array design, research shows

Scientists have pioneered a new technique to produce arrays of sound produced entirely by heat.

Looping X-rays to produce higher quality laser pulses

Ever since 1960, when Theodore Maiman built the world's first infrared laser, physicists dreamed of producing X-ray laser pulses that are capable of probing the ultrashort and ultrafast scales of atoms and molecules.

New method measures temperature within 3-D objects

University of Wisconsin-Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in applications where traditional temperature probes won't work, like monitoring semiconductor performance or next-generation nuclear reactors.

A path to new nanofluidic devices applying spintronics technology

Researchers in the ERATO Saitoh Spin Quantum Rectification Project in the JST Strategic Basic Research Programs have elucidated the mechanism of the hydrodynamic power generation using spin currents in micrometer-scale channels, finding that power generation efficiency improves drastically as the size of the flow is made smaller.

Spintronics: Faster data processing through ultrashort electric pulses

Physicists at Martin Luther University Halle-Wittenberg (MLU) and Lanzhou University in China developed a simple concept that could significantly improve magnetic-based data processing. Using ultrashort electric pulses in the terahertz range, data can be written, read and erased very quickly. This would make data processing faster, more compact and energy efficient. The researchers confirmed their theory by running complex simulations, and the results were published in the journal NPG Asia Materials.

Astronomy and Space news

Astronomers observe nova V659 Sct during outburst

Using the TIGRE telescope, astronomers have conducted spectroscopic observations of recently discovered nova known as V659 Sct during multiple phases of its outburst. Results of this observational campaign, presented in a paper published June 24 on the arXiv pre-print server, shed more light on the properties of this event.

Mini-marsquakes measured by InSight lander show effects of sun and wind

Compared with our own planet Earth, Mars might seem like a "dead" planet, but even there, the wind blows and the ground moves. On Earth, we study the ambient seismic noise rippling mainly due to ocean activity to peek underground at the structure of the Earth's interior. Can we do the same on Mars, without an ocean?

Discovery of a luminous galaxy reionizing the local intergalactic medium 13 billion years ago

Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang. The research, led by Romain Meyer, Ph.D. student at UCL in London, UK, has been presented today at the virtual annual meeting of the European Astronomical Society (EAS).

Stellar fireworks celebrate birth of giant cluster

Astronomers created a stunning new image showing celestial fireworks in star cluster G286.21+0.17.

Image: Hubble spots feathered spiral

The spiral pattern shown by the galaxy in this image from the NASA/ESA Hubble Space Telescope is striking because of its delicate, feathery nature. These "flocculent" spiral arms indicate that the recent history of star formation of the galaxy, known as NGC 2775, has been relatively quiet. There is virtually no star formation in the central part of the galaxy, which is dominated by an unusually large and relatively empty galactic bulge, where all the gas was converted into stars long ago.

Gaia revolutionises asteroid tracking

ESA's Gaia space observatory is an ambitious mission to construct a three-dimensional map of our galaxy by making high-precision measurements of over one billion stars. However, on its journey to map distant suns, Gaia is revolutionising a field much closer to home. By accurately mapping the stars, it is helping researchers track down lost asteroids.

Unprecedented ground-based discovery of two strongly interacting exoplanets

Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.

Scientists detect rapid changes in a black hole that may explain gamma-ray bursts

Some of the most massive and distant black holes in the universe emit an enormous amount of extraordinarily energetic radiation called gamma rays. This type of radiation occurs, for example, when mass is converted into energy during fission reactions that run nuclear reactors on Earth. But in the case of black holes, gamma radiation is even more energetic than that produced in nuclear reactors and is the product of very different processes; there, the gamma rays are created by collisions between light rays and highly energetic particles born in the vicinity of black holes by means of mechanisms that are still poorly understood.

Video: Flight over Korolev Crater on Mars

This movie was created using an image mosaic made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express, which was first published in December 2018. The mosaic combines data from the HRSC nadir and colour channels; the nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface.

Technology news

Dye-sensitized solar cells that adapt to different light conditions

Solar cells made of semi-transparent photovoltaic (PV) materials typically have a fixed optical transmission, which results in either high transparency or high efficiency, but rarely both. In order to perform optimally when integrated on buildings, however, they should be able to generate electricity efficiently, while also changing how much they transmit light based on the intensity of natural light in their surroundings.

Facebook designs ultra-thin VR eyeglasses

Facebook said this week it has developed the thinnest virtual reality headset in the world. Although it remains a prototype for now, the device does away with the bulky boxlike headgear commonly associated with virtual reality setups and instead sports the look of a large pair of sunglasses with lenses just under .3 inches thick.

White Rabbit, a CERN-born technology, sets a new global standard

White Rabbit (WR) is a technology developed at CERN to provide the LHC accelerator chain with deterministic data transfer, sub-nanosecond accuracy and a synchronization precision of a few picoseconds. First used in 2012, the technology has since then expanded its applications outside the field of particle physics and is now deployed in numerous scientific infrastructures worldwide. It has shown its innovative potential by being commercialized and introduced into different industries, including telecommunications, financial markets, smart grids, the space industry and quantum computing.
