Research predicts the high-temperature topological superconductivity of twisted double-layer copper oxides

Two-dimensional (2D) materials, such as graphene or transition metal dichalcogenides, can sometimes be assembled into bilayers with a twist between individual layers. In recent years, many researchers have been investigating the properties of these twisted double-layer structures and their potential advantages for fabricating electronic devices.

IceCube detection of a high-energy particle proves 60-year-old theory

On December 6, 2016, a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly decayed into a shower of secondary particles. The interaction was captured by a massive telescope buried in the Antarctic glacier, the IceCube Neutrino Observatory.

Using artificial intelligence to generate 3D holograms in real-time

Despite years of hype, virtual reality headsets have yet to topple TV or computer screens as the go-to devices for video viewing. One reason: VR can make users feel sick. Nausea and eye strain can result because VR creates an illusion of 3D viewing although the user is in fact staring at a fixed-distance 2D display. The solution for better 3D visualization could lie in a 60-year-old technology remade for the digital world: holograms.

Finding quvigints in a quantum treasure map

Researchers have struck quantum gold—and created a new word—by enlisting machine learning to efficiently navigate a 20-dimensional quantum treasure map.

Searching for elusive supersymmetric particles

The Standard Model of particle physics is the best explanation to date for how the universe works at the subnuclear level and has helped explain, correctly, the elementary particles and forces between them. But the model is incomplete, requiring "extensions" to address its shortfalls.

Creating a new type of computing that's 'naturally probabilistic'

"You see, nature is unpredictable. How do you expect to predict it with a computer?" said American physicist Richard Feynman before computer scientists at a conference in 1981.

A theoretical path to polarized electron-beam nano-spectroscopy

A trio of researchers from the University of Göttingen, Université de Technologie de Troyes and Université Paris-Saclay, has developed a theoretical path to polarized electron-beam nano-spectroscopy. In their paper published in the journal Nature Physics, Hugo Lourenço-Martins, Davy Gérard and Mathieu Kociak, outline a theory that involves establishing a relationship between polarized optical spectroscopy and scattering of free electrons. David Masiello with the University of Washington has published a News & Views piece in the same journal issue outlining the work by the researchers.

How the electronic properties and atomic vibrations of uranium are linked

Researchers have explained how the electronic properties and atomic vibrations of uranium are linked.

Physics undergraduate proposes solution to quantum field theory problem

When physicists need to understand the quantum mechanics that describe how atomic clocks work, how your magnet sticks to your refrigerator or how particles flow through a superconductor, they use quantum field theories.

How a ladybug warps space-time

Researchers at the University of Vienna and the Austrian Academy of Sciences, led by Markus Aspelmeyer have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum—and thus the smallest gravitational force. The experiment opens up new possibilities for testing the laws of gravity on previously unattained small scales. The results are published in the journal Nature.

Bacteria know how to exploit quantum mechanics, study finds

LS2 report: CERN's oldest accelerator awakens

"Synchrotron (PS) is the beating heart of CERN's accelerator system. Situated at the center of the complex, it feeds particle beams not only to the Large Hadron Collider (LHC), but to many of CERN's major facilities, including the Antimatter Factory and the East Area." Klaus Hanke, head of the Proton Synchrotron operations team, chooses his words carefully to describe CERN's oldest accelerator still in operation. On 4 March, the veteran accelerator received its first particle beam after a two-year shutdown, during which it underwent significant upgrades to prepare it for higher luminosity (an indicator of the number of collisions).

Scientists have synthesized a new high-temperature superconductor

An international team led by Artem R. Oganov, a Professor at Skoltech and MISIS, and Dr. Ivan Troyan from the Institute of Crystallography of RAS performed theoretical and experimental research on a new high-temperature superconductor, yttrium hydride (YH6). Their findings were published in the journal Advanced Materials.

The observations revealed that this object is an SU UMa-type dwarf nova. The finding is reported in a paper published March 4 on the arXiv pre-print server.

Explaining Parker Solar Probe's magnetic puzzle

When NASA's Parker Solar Probe sent back the first observations from its voyage to the Sun, scientists found signs of a wild ocean of currents and waves quite unlike the near-Earth space much closer to our planet. This ocean was spiked with what became known as switchbacks: rapid flips in the Sun's magnetic field that reversed direction like a zig-zagging mountain road.

Ideas for future NASA missions searching for extraterrestrial civilizations

A researcher at the Instituto de Astrofísica de Canarias (IAC) is the lead author of a study with proposals for 'technosignatures'—evidence for the use of technology or industrial activity in other parts of the Universe—for future NASA missions.

How scientists found rare fireball meteorite pieces on a driveway—and what they can teach us

As people in the UK were settling down to watch the late evening news on February 28, a fresh news story, quite literally, appeared in the night sky. A large and very bright fireball was seen over southern England and northern France at 21:54 GMT. It was recorded by many doorbell webcams, so it was a very well-observed fireball. More importantly, it was also captured by the automated cameras of the UK Meteor Observation Network and similar networks.

In first, scientists trace fastest solar particles to their roots on the Sun

Zipping through space at close to the speed of light, Solar Energetic Particles, or SEPs, are one of the main challenges for the future of human spaceflight. Clouds of these tiny solar projectiles can make it to Earth—a 93 million mile journey—in under an hour. They can fry sensitive spacecraft electronics and pose serious risks to human astronauts. But their onset is extraordinarily hard to predict, in part because we still don't know exactly where on the Sun they come from.
