ALPHA collaboration reports first measurements of certain quantum effects in antimatter

The ALPHA collaboration at CERN has reported the first measurements of certain quantum effects in the energy structure of antihydrogen, the antimatter counterpart of hydrogen. These quantum effects are known to exist in matter, and studying them could reveal as yet unobserved differences between the behavior of matter and antimatter. The results, described in a paper published today in the journal Nature, show that these first measurements are consistent with theoretical predictions of the effects in "normal" hydrogen, and pave the way for more precise measurements of these and other fundamental quantities.

10,000 times faster calculations of many-body quantum dynamics possible

How an electron behaves in an atom, or how it moves in a solid, can be predicted precisely with the equations of quantum mechanics. These theoretical calculations agree fully with the results obtained from experiments. But complex quantum systems, which contain many electrons or elementary particles—such as molecules, solids or atomic nuclei—can currently not be described exactly, even with the most powerful computers available today. The underlying mathematical equations are too complex, and the computational requirements are too large. A team led by Professor Michael Bonitz from the Institute of Theoretical Physics and Astrophysics at Kiel University (CAU) has now succeeded in developing a simulation method, which enables quantum mechanical calculations up to around 10,000 times faster than previously possible. They have published their findings in the current issue of the renowned scientific journal Physical Review Letters.

Carrier-assisted differential detection

Hyperscale datacenters have sprung up across the globe rapidly. This generate tremendous demand for high-capacity, cost-effective optical communication links that interconnect them. Engineers at the University of Melbourne invented an innovative signal reception scheme tailored for datacenter applications where the complex-valued double-sideband signals can be recovered via direct detection. The receiver architecture opens a new class of direct detection schemes that are suitable for photonic integration analogous to homodyne receivers in coherent detection.

Laser writing enables practical flat optics and data storage in glass

Femtosecond laser machining has emerged as an attractive technology enabling applications ranging from eye surgery to direct writing on the bulk of transparent materials. Scientists from the University of Southampton, UK, demonstrated a new regime of ultrafast laser writing in silica glass, which produces anisotropic nanostructures and related birefrigence with negligible transmission loss. The technology enables practical wavefront shaping with flat optics and polarization beam shaping of high power lasers from ultraviolet to infrared, as well as high-capacity optical data storage.

Astronomy & Space news

How newborn stars prepare for the birth of planets

An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the earliest stages of star formation.

Beyond the brim, Sombrero Galaxy's halo suggests turbulent past

Surprising new data from NASA's Hubble Space Telescope suggests the smooth, settled "brim" of the Sombrero galaxy's disk may be concealing a turbulent past. Hubble's sharpness and sensitivity resolves tens of thousands of individual stars in the Sombrero's vast, extended halo, the region beyond a galaxy's central portion, typically made of older stars. These latest observations of the Sombrero are turning conventional theory on its head, showing only a tiny fraction of older, metal-poor stars in the halo, plus an unexpected abundance of metal-rich stars typically found only in a galaxy's disk, and the central bulge. Past major galaxy mergers are a possible explanation, though the stately Sombrero shows none of the messy evidence of a recent merger of massive galaxies.

Eighteen-hour-year planet on edge of destruction

Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type.

Sub-Neptune sized planet validated with the habitable-zone planet finder

A signal originally detected by the Kepler spacecraft has been validated as an exoplanet using the Habitable-zone Planet Finder (HPF), an astronomical spectrograph built by a Penn State team and recently installed on the 10m Hobby-Eberly Telescope at McDonald Observatory in Texas. The HPF provides the highest precision measurements to date of infrared signals from nearby low-mass stars, and astronomers used it to validate the candidate planet by excluding all possibilities of contaminating signals to very high level of probability. The details of the findings appear in the Astronomical Journal.

Journey to the center of Mars: A new compositional model for the red planet

While InSight's seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, Takashi Yoshizaki (Tohoku University) and Bill McDonough (Tohoku University and University of Maryland, College Park), have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to its core-mantle boundary, some 1,800 km beneath the surface and have been able to suggest that its core contains moderate amounts of sulfur, oxygen and hydrogen as light elements.

Stargazing with computers: What machine learning can teach us about the cosmos

Gazing up at the night sky in a rural area, you'll probably see the shining moon surrounded by stars. If you're lucky, you might spot the furthest thing visible with the naked eye—the Andromeda galaxy. It's the nearest neighbor to our galaxy, the Milky Way. But that's just the tiniest fraction of what's out there. When the Department of Energy's (DOE) Legacy Survey of Space and Time (LSST) Camera at the National Science Foundation's Vera Rubin Observatory turns on in 2022, it will take photos of 37 billion galaxies and stars over the course of a decade.

Scientists Scanned Brains of Bullies and Found Something Grim

An international team of neuroscientists scanned the brains of lifelong bullies and found something grim: Bullies' brains appear to be physically smaller than other brains.

"Our findings support the idea that, for the small proportion of individuals with life-course-persistent antisocial behaviour, there may be differences in their brain structure that make it difficult for them to develop social skills that prevent them from engaging in antisocial behaviour," said lead author Christina Carlisi, a researcher at the University College London.

American Doctors Are Bracing For a Global COVID-19 Pandemic

It might be time to start preparing yourself for a coronavirus pandemic. CNBC reports that American doctors are worried that if the COVID-19 epidemic spreads beyond a few isolated cases in the United States, it could lead to a crisis as patients overwhelm emergency rules and exhaust stores of medical supplies. "This is the time to open up your pandemic plans and see that things are in order," Dr. Anne Schuchat, an official at the Centers for Disease Control and Prevention, warned.
