Scientists discover crystal exhibiting exotic spiral magnetism

Posted by in categories: materials, particle physics

An exotic form of magnetism has been discovered and linked to an equally exotic type of electrons, according to scientists who analyzed a new crystal in which they appear at the National Institute of Standards and Technology (NIST). The magnetism is created and protected by the crystal’s unique electronic structure, offering a mechanism that might be exploited for fast, robust information storage devices.

The newly invented material has an unusual structure that conducts electricity but makes the flowing electrons behave as massless particles, whose is linked to the direction of their motion. In other materials, such Weyl electrons have elicited new behaviors related to electrical conductivity. In this case, however, the electrons promote the spontaneous formation of a magnetic spiral.

“Our research shows a rare example of these particles driving collective magnetism,” said Collin Broholm, a physicist at Johns Hopkins University who led the at the NIST Center for Neutron Research (NCNR). “Our experiment illustrates a unique form of magnetism that can arise from Weyl electrons.”

Levitation: Classic Magic Trick May Enable Quantum Computing

Posted by in categories: computing, particle physics, quantum physics

A new project will use the electric field in an accelerator cavity to try to levitate a tiny metallic particle, allowing it to store quantum information.

Quantum computing could solve problems that are difficult for traditional computer systems. It may seem like magic. One step toward achieving quantum computing even resembles a magician’s trick: levitation. A new project at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility will attempt this trick by levitating a microscopic particle in a superconducting radiofrequency (SRF) cavity to observe quantum phenomena.

Typically at Jefferson Lab and other particle accelerator facilities, SRF cavities enable studies of the atom.

These electric submarines map the seafloor to make way for wind power

Posted by in categories: robotics/AI, sustainability, transportation

In March, the departments of Energy, Interior and Commerce said they were aiming for U.S. offshore wind capacity to hit 30 gigawatts (GW) by 2,030 a hugely optimistic goal that would require thousands of new wind turbines to be installed off the Atlantic, Pacific and Gulf coasts.

With federal support locked in, now it’s up to developers and operators to figure out where it’s safe to install offshore wind farms and pursue permits.

Bedrock, a Richmond, California, start-up, wants to help them map the seafloor using electric autonomous underwater vehicles (e-AUV) that can launch right from the shore.

Facebook launches VR remote work app, calling it a step to the ‘metaverse’

Posted by in categories: biotech/medical, computing, virtual reality

In its first full VR news briefing, the company showed how Workrooms users can design avatar versions of themselves to meet in virtual reality conference rooms and collaborate on shared whiteboards or documents, still interacting with their own physical desk and computer keyboard.

Aug 19 (Reuters) — Facebook Inc (FB.O) on Thursday launched a test of a new virtual-reality remote work app where users of the company’s Oculus Quest 2 headsets can hold meetings as avatar versions of themselves.

The beta test of Facebook’s Horizon Workrooms app comes as many companies continue to work from home after the COVID-19 pandemic shut down physical workspaces and as a new variant is sweeping across the globe.
