Two different experiments on two different transition metals reveal that a current of electron orbital angular momentum flows in response to an electric field.

In the spin Hall effect, an applied electric field drives a current of electron spin in a direction transverse to the field. In a transition metal, theorists predict that an orbital angular momentum (OAM) current can also flow. Now two groups have independently observed this so-called orbital Hall effect (OHE) [1, 2]. These observations supplement one made by a third group earlier this year [3]. Together these demonstrations constitute a step toward the development of “orbitronic” devices based on an electron’s orbital degree of freedom.

For their demonstration, Giacomo Sala of the Swiss Federal Institute of Technology (ETH) in Zurich and his colleagues turned to a phenomenon known as Hanle magnetoresistance. In a conductor, when a magnetic field is applied parallel to the direction of electron OAM, orbital moments should accumulate at the edges of the sample because of the OHE. If instead the field is applied perpendicular to electron OAM, the orbital moments should precess. The orbital moments should then fall out of phase with each other, which boosts the material’s magnetoresistance. The team observed these effects in thin films of manganese [1].

New Horizons’ mission of exploration of the outer solar system will continue, according to a recently announced updated plan from NASA.

Beginning in fiscal year 2025, New Horizons will focus on gathering unique heliophysics data, which can be readily obtained during an extended, low-activity mode of operations.

In a surprising new study, researchers at the University of Minnesota Twin Cities have found that the electron beam radiation that they previously thought degraded crystals can actually repair cracks in these nanostructures.

The groundbreaking discovery provides a new pathway to create more perfect crystal nanostructures, a process that is critical to improving the efficiency and cost-effectiveness of materials that are used in virtually all electronic devices we use every day.

“For a long time, researchers studying nanostructures were thinking that when we put the crystals under electron beam radiation to study them that they would degrade,” said Andre Mkhoyan, a University of Minnesota chemical engineering and materials science professor and lead researcher in the study. “What we showed in this study is that when we took a crystal of titanium dioxide and irradiate it with an electron beam, the naturally occurring narrow cracks actually filled in and healed themselves.”

AI is so energy-hungry that most data analysis must be performed in the cloud New energy-efficient device enables AI tasks to be performed within wearables This allows real-time analysis and diagnostics for faster medical interventions Researchers tested the device by classifying 10,000 ele.

“The surprising thing we found is that in a particular kind of crystal lattice, where electrons become stuck, the strongly coupled behavior of electrons in d atomic orbitals actually act like the f orbital systems of some heavy fermions,” said Qimiao Si, co-author of a study about the research in Science Advances

<em> Science Advances </em> is a peer-reviewed, open-access scientific journal that is published by the American Association for the Advancement of Science (AAAS). It was launched in 2015 and covers a wide range of topics in the natural sciences, including biology, chemistry, earth and environmental sciences, materials science, and physics.

Oh boy. What could go wrong?

Scientists trying to take advantage of the unusual properties of the quantum realm say they have successfully simulated a method of backward time travel that allowed them to change an event after the fact one out of four times. The Cambridge University team is quick to caution that they have built a time machine, per se, but also note how their process doesn’t violate physics while changing past events after they have happened.

“Imagine that you want to send a gift to someone: you need to send it on day one to make sure it arrives on day three,” explained lead author David Arvidsson-Shukur from the Cambridge Hitachi Laboratory. “However, you only receive that person’s wish list on day two.”
