Superconductivity that shouldn’t exist: Physicists dissect the mind-boggling properties of a strange quantum material

The material UTe2 exhibits multiple forms of zero electrical resistance—a phenomenon known as superconductivity—and displays several puzzling properties. After UTe2 loses its superconductivity at a certain magnetic field, it becomes superconducting again under much higher fields.

Using a new high-field measurement technique, researchers from the Institute of Science and Technology Austria (ISTA) have explained this unusual superconducting behavior in a paper in Nature Communications. Their method is now being adopted at high-field laboratories worldwide.

Quantum materials exhibit exotic properties that make them relevant for next-generation technologies. While some scientists researching quantum materials seek to uncover specific properties for targeted applications, such as quantum computing, other researchers are curiosity-driven, searching for knowledge that hasn’t yet appeared in textbooks.

How a free flow of information can amplify incorrect ideas

The idea that information should flow freely is deeply embedded in the design of social media. The assumption is that the more information is produced and shared, the better. However, simulations by a team of scientists including University of Groningen Professor of Artificial Intelligence Davide Grossi show that such an unrestricted flow of information can amplify incorrect ideas among like-minded people. The study is published in Proceedings of the National Academy of Sciences.

Information sharing is always beneficial. That is the central premise of digital communication platforms. If users want to communicate with one another, no amount of shared information is too much. But is this central premise correct? A team of social scientists and computer scientists used digital agents that shared unlimited information with perfect honesty to study how this affected the development of correct and incorrect ideas.

A mechanical blue LED: Stretching GaN shifts light from UV to blue without changing chemistry

A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical stretching technology to dynamically control the emission color of gallium nitride (GaN) material from ultraviolet (UV) to blue light. This technological breakthrough provides a new semiconductor material control solution for future advanced power transistors, optoelectronic components, radio frequency components, and micro-LED displays.

The findings have been published in Physical Review X in a paper titled “Deep Elastic Strain Engineering of Free-Standing GaN Microbridge.”

Led by Professor Yang Lu from the Department of Mechanical Engineering, the team utilized micro-nano processing technology to fabricate single-crystalline GaN material into tiny bridge-like structures.

Scientists create electronic devices that function reliably at extreme temperatures from 500 degrees Celcuis to absolute zero — advanced semiconductor material unlocks new possibilities in space tech and quantum computing

The technology has massive potential in space technology and quantum computing

Fragile no more, nickelates get an upgrade that changes how superconductivity endures

Discovered in 2019, the material known as nickelates has intrigued researchers for its potential to become a superconductor at elevated temperatures—a property that could significantly advance such fields as quantum science and energy transmission. However, it’s a very unstable material and difficult to work with. But the lab of Professor Charles Ahn has developed a method that could enhance superconductivity in these materials. The results are published in Nature Communications.

With their ability to conduct electricity with no resistance, superconductors are a key component to quantum computing, medical imaging, and a number of other fields. A group of copper-oxide compounds known as cuprates have long been central to the study of high-temperature superconductivity (“high temperature” is a relative term—they still need to be kept in very cold environments). Nickelates are especially exciting because they share some of cuprates’ key electronic features while offering a new platform for materials design and tuning.

Enter nickelates, a material with many similarities to cuprates, but with the potential to eventually become even more useful to scientists. Dung Vu, a postdoctoral associate who led the study, noted that synthesizing nickelate thin films is “notoriously difficult.” The Ahn lab is one of the few in the world with the ability to do so.
