Study uncovers broken mirror symmetry in the Fermi-liquid-like phase of a cuprate

Posted by in categories: materials, physics

Materials that exhibit superconducting properties at high temperatures, known as high-temperature superconductors, have been the focus of numerous recent studies, as they can be used to develop new technologies that perform well at higher temperatures. Although high-temperature superconductivity has been widely investigated, its underlying physics is not yet fully understood.

Superconductivity study confirms existence of edge supercurrents

Posted by in categories: materials, space

Topological materials are materials that have unusual properties that arise because their wavefunction—the physical law guiding the electrons—is knotted or twisted. Where the topological material meets the surrounding space, the wavefunction must unwind. To accommodate this abrupt change, the electrons at the edge of the material must behave differently than they do in the main bulk of the material.

Kagome Metals Unlocked: A New Dimension of Superconductivity

Posted by in categories: materials, quantum physics

Kagome metals exhibit superconductivity through a unique wave-like distribution of electron pairs, a discovery that overturns previous assumptions and may lead to the development of novel superconducting components.

This groundbreaking research, driven by theoretical insights and enhanced by cutting-edge experimental techniques, marks a significant step towards realizing efficient quantum devices.

For about fifteen years, Kagome materials with their star-shaped structure reminiscent of a Japanese basketry pattern have captivated global research. Only staring from 2018 scientists have been able to synthesize metallic compounds featuring this structure in the lab. Thanks to their unique crystal geometry, Kagome metals combine distinctive electronic, magnetic, and superconducting properties, making them promising for future quantum technologies.

Unlocking the Secrets of Promethium: Scientists Capture a Never-Before-Seen Elemental Bond

Posted by in categories: chemistry, materials

A team of scientists led by the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) recently made an unprecedented observation of how promethium, a rare element, forms chemical bonds in aqueous solutions.

This groundbreaking discovery was made using the Beamline for Materials Measurement (BMM), a beamline funded and operated by the National Institute of Standards and Technology, at the National Synchrotron Light Source II, a DOE Office of Science user facility at DOE’s Brookhaven National Laboratory.

Scientists develop new artificial intelligence method to create material ‘fingerprints’

Posted by in categories: materials, robotics/AI

Researchers at Argonne have developed an innovative technique that creates “fingerprints” of different materials that can be read and analyzed by a neural network to yield previously inaccessible information — https://bit.ly/3LCklZw.

The goal of the AI is just to treat the scattering patterns as…

Meissner Effect

Posted by in category: materials

A permanent magnet begins to hover above a ceramic material as it cools and transitions to a superconducting state; the magnet remains aloft until the ceramic warms above a critical temperature.

The ceramic material is a 25mm disc of yttrium barium copper oxide (YBa2Cu3O7, also commonly referred to as \.
