Physics news

A perovskite-based diode capable of both light emission and detection

Light sources and detectors are key components of countless technological devices on the market today. For instance, light emitting diodes (LEDs) are often used as a source of light in displays and other technologies, while photodiodes are used to detect light in sensors, imaging and fiber optic communication tools.

Self-powered X-ray detector to revolutionize imaging for medicine, security and research

A new X-ray detector prototype is on the brink of revolutionizing medical imaging, with dramatic reduction in radiation exposure and the associated health risks, while also boosting resolution in security scanners and research applications, thanks to a collaboration between Los Alamos National Laboratory and Argonne National Laboratory researchers.

First sighting of mysterious Majorana fermion on a common metal

Physicists at MIT and elsewhere have observed evidence of Majorana fermions—particles that are theorized to also be their own antiparticle—on the surface of a common metal: gold. This is the first sighting of Majorana fermions on a platform that can potentially be scaled up. The results, published in the Proceedings of the National Academy of Sciences, are a major step toward isolating the particles as stable, error-proof qubits for quantum computing.

New protocol identifies fascinating quantum states

Topological materials attract great interest and may provide the basis for a new era in materials development. In Science Advances, physicists around Andreas Elben, Jinlong Yu, Peter Zoller and Benoit Vermersch now present a new measuring method to identify and characterize so-called topological invariants on various experimental platforms.

In a first, researchers use ultrafast 'electron camera' to learn about molecules in liquid samples

High-speed "electron cameras" can detect tiny molecular movements in a material by scattering a powerful beam of electrons off a sample. Until recently, researchers had only used this technique to study gases and solids. But some of the most important biological and chemical processes, in particular the conversion of light into energy, happen in molecules in a solution.

The cold eyes of DUNE: International Deep Underground Neutrino Experiment

How do you detect a particle that has almost no mass, feels only two of the four fundamental forces, and can travel unhindered through solid lead for an entire light-year without ever interacting with matter? This is the problem posed by neutrinos, ghostly particles that are generated in the trillions by nuclear reactions in stars, including our sun, and on Earth. Scientists can also produce neutrinos to study in controlled experiments using particle accelerators. One of the ways neutrinos can be detected is with large vats filled with liquid argon and wrapped with a complex web of integrated circuitry that can operate in temperatures colder than the average day on Neptune.

Anyon evidence observed using tiny anyon collider

A team of researchers from Sorbonne Université and Université de Paris has reported observational evidence of a quasiparticle called an anyon. In their paper published in the journal Science, the team describes the tiny anyon collider they built in the lab their results. Dmitri Feldman, with Brown University has published a Perspective piece on the work in the same journal issue.

Research links elastodynamic and electromagnetic wave phenomena

Imagine the advances to predictive modeling if you could infer something about how light amplifies colors in a bird's plumage from the way seismic waves propagate through mountain systems.

Researchers demonstrate a platform for future optical transistors

Leading research groups in the field of nanophotonics are working toward developing optical transistors—key components for future optical computers. These devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem for microelectronics engineers. A group of researchers from ITMO University, together with colleagues, have come up with a new solution to this problem by creating a planar system where photons couple to other particles, which enables them to interact with each other. The principle demonstrated in their experiment can provide a platform for developing future optical transistors. The results of their work are published in Light: Science & Applications.

Magnet research takes giant leap

Researchers pushing the limits of magnets as a means to create faster electronics published their proof of concept findings today, April 10, in the journal Science. The University of Central Florida is the lead university in the multidisciplinary university research initiative (MURI) project. The team exploring methods for creating machines that operate at trillions of cycles per second includes the University of California, Santa Cruz and Riverside, Ohio State University, Oakland University (Michigan) and New York University, among others.

Astronomy and Space news

Rehearsal time for NASA's asteroid sampling spacecraft

In August, a robotic spacecraft will make NASA's first-ever attempt to descend to the surface of an asteroid, collect a sample, and ultimately bring it safely back to Earth. In order to achieve this challenging feat, the OSIRIS-REx mission team devised new techniques to operate in asteroid Bennu's microgravity environment—but they still need experience flying the spacecraft in close proximity to the asteroid in order to test them. So, before touching down at sample site Nightingale this summer, OSIRIS-REx will first rehearse the activities leading up to the event.

Help pave the way for Artemis: Send NASA your mini moon payload designs

Future exploration of the Moon and beyond will require tools of all shapes and sizes—from sweeping orbiters to the tiniest of rovers. In addition to current planned scientific rovers like the Volatiles Investigating Polar Exploration Rover, or VIPER, NASA could one day send even smaller rovers to help scout the Moon's surface. These tiny robots would provide mission flexibility and collect key information about the lunar surface, its resources and the environment. The data collected by these rovers would be helpful for future lunar endeavors and NASA's Artemis program.

How did the TRAPPIST-1 planets get their water?

In 2017, an international team of astronomers announced a momentous discovery. Based on years of observations, they found that the TRAPPIST-1 system (an M-type red dwarf located 40 light-years from Earth) contained no less than seven rocky planets. Equally exciting was the fact that three of these planets were found within the star's habitable zone (HZ), and that the system itself has had 8 billion years to develop the chemistry for life.

Piercing the dark birthplaces of massive stars with Webb

High-mass stars, which are eight or more times the mass of our Sun, live hard and die young. They often end their short lives in violent explosions called supernovas, but their births are much more of a mystery. They form in very dense, cold clouds of gas and dust, but little is known about these regions. In 2021, shortly after the launch of NASA's James Webb Space Telescope, scientists plan to study three of these clouds to understand their structure.
