A University of Minnesota Twin Cities-led research team has solved a longstanding mystery surrounding strontium titanate, an unusual metal oxide that can be an insulator, a semiconductor, or a metal. The research provides insight for future applications of this material to electronic devices and data storage.

The paper is published in the Proceedings of the National Academy of Sciences.

When an insulator like strontium titanate is placed between oppositely charged metal plates, the electric field between the plates causes the negatively charged electrons and the positive nuclei to line up in the direction of the field. This orderly lining up of electrons and nuclei is resisted by thermal vibrations, and the degree of order is measured by a fundamental quantity called the dielectric constant. At low temperature, where the thermal vibrations are weak, the dielectric constant is larger.

Moving beyond I2C, Renesas is introducing a new I3C intelligent switch family to boost performance and speed in the data center.

Few fields are as dynamic and fast-evolving as the data center. With new software, use-cases, and applications popping up every year, the underlying hardware has become increasingly difficult to keep up with.

One relatively new technology designed to improve upon legacy hardware is I3C, the successor to conventional I2C. Boasting improvements on I2C, I3C has still yet to become widespread in the data center, a place where its value could be significant.

Alongside a new upgrade kit, the company is also introducing a second-generation Framework laptop with a stronger lid.

AMD has shown off Zen 4 overclocking at Computex but questions remain about the chip’s long-term potential and OC performance.

APIs have catalyzed the evolution of the internet and could evolve into the brain-computer interface-driven metaverse reality on the horizon.

It’s amazing how simple designs can save you from hours of frustration and embarrassment, even virtually.

Work and School from Home arrangements have forced many people to get used to video meetings, virtual classrooms, and online presentations. As if those weren’t stressful enough already, the horrors of discovering that you have been speaking for the past 10 minutes to half an hour when you’re mic has been on mute all the time only adds to feelings of dread. Unfortunately, computers and software haven’t adjusted yet to these new demands on life, lacking clear indicators on the status of the mic. While there might be some sophisticated and complicated software that could try to guess whether you actually need to be muted or not, it actually takes a dead-simple idea to give that peace of mind at very little extra cost.

Researchers at Duke University and the University of Maryland have used the frequency of measurements on a quantum computer to get a glimpse into the quantum phenomena of phase changes—something analogous to water turning to steam.

By measuring the number of operations that can be implemented on a quantum computing system without triggering the collapse of its quantum state, the researchers gained insight into how other systems—both natural and computational—meet their tipping points between phases. The results also provide guidance for computer scientists working to implement quantum error correction that will eventually enable quantum computers to achieve their full potential.

The results appeared online June 3 in the journal Nature Physics.
