If you wanted to deliver a package across the street and avoid being hit by a car, you could program a powerful computer to do it, equipped with sensors and hardware capable of running multiple differential equations to track the movement and speed of each car. But a young child would be capable of doing the same task with little effort, says Alex Demkov, professor of physics at The University of Texas at Austin.

Last year, scientists demonstrated that twisted bilayer graphene — a material made of two atom-thin sheets of carbon with a slight twist — can exhibit alternating superconducting and insulating regions. Now, a new study in the journal Nature by scientists from Spain, the U.S., China and Japan shows that superconductivity can be turned on or off with a small voltage change, increasing its usefulness for electronic devices.

Feliciano Giustino recently joined the University of Texas at Austin faculty in the Department of Physics and is a Moncrief Chair in the Oden Institute for Computational Engineering and Sciences, where he will direct the Center for Quantum Materials Engineering. He was previously a professor in the Department of Materials at Oxford University.

As computers advance, encryption methods currently used to keep everything from financial transactions to military secrets secure might soon be useless, technology experts warn. Reporting today in the journal Nature, a team of physicists and engineers led by University of Texas at Austin physics professor Xiaoqin Elaine Li report they have created a material with light-emitting properties that might enable hack-proof communications, guaranteed by the laws of quantum mechanics.

Over the past few decades, the cost of storing data on hard disk drives (HDDs) has fallen dramatically, enabling revolutions in personal, scientific and cloud computing and allowing for storage of ever-greater amounts of data. But even as data collection continues to skyrocket, the cost-per-bit trend has been flattening out, leading to calls for new innovations in technology.

A nearly $7 million grant from NASA is supporting research to develop approaches to detecting extraterrestrial life, and two University of Texas at Austin faculty are part of the interdisciplinary scientific team.

Researchers in the Cockrell School of Engineering and the College of Natural Sciences at The University of Texas at Austin have received a $15.6 million grant from the National Science Foundation (NSF) to discover and advance new types of materials for use in many applications including energy storage, medical devices and information processing.

A research team led by physics professor Keji Lai at the University of Texas at Austin has discovered that a material he studies has an unusual property that could one day lead to cell phones and other electronic devices that are smaller, lighter and more energy efficient.

Salt, snowflakes and diamonds are all crystals, meaning their atoms are arranged in 3-D patterns that repeat. Today scientists are reporting in the journal Nature on the creation of a phase of matter, dubbed a time crystal, in which atoms move in a pattern that repeats in time rather than in space.
