A bridge to the quantum world

Monika Aidelsburger uses a special type of optical lattice to simulate quantum many-body phenomena that are otherwise inaccessible to experimental exploration. She has now been awarded an ERC Starting Grant to pursue this work.

Understanding the building blocks for an electronic brain

Computer bits are binary, with a value of zero or one. By contrast, neurons in the brain can have many internal states, depending on the input that they receive. This allows the brain to process information in a more energy-efficient manner than a computer. University of Groningen (UG) physicists are working on memristors made from niobium-doped strontium titanate, which mimic the function of neurons. Their results were published in the Journal of Applied Physics on 21 October.

Stephen Hawking's wheelchair, thesis for sale

Stephen Hawking was a cosmic visionary, a figure of inspiration and a global celebrity.

Merging mathematical and physical models toward building a more perfect flying vehicle

When designing flying vehicles, there are many aspects of which we can be certain but there are also many uncertainties. Most are random, and others are just not well understood. University of Illinois Professor Harry Hilton brought together several mathematical and physical theories to help look at problems in more unified ways and solve physical engineering problems.

A new way to measure nearly nothing

Scientists have designed a vacuum gauge, based on ultracold trapped atoms, is small enough to deploy in commonly used vacuum chambers.

Surprise finding: Discovering a previously unknown role for a source of magnetic fields

Feature describes unexpected discovery of a role the process that seeds magnetic fields plays in mediating a phenomenon that occurs throughout the universe and can disrupt cell phone service and knock out power grids on Earth.

Molecular memory can be used to increase the memory capacity of hard disks

Scientists have taken part in research where the first molecule capable of remembering the direction of a magnetic above liquid nitrogen temperatures has been prepared and characterized. The results may be used in the future to massively increase the storage capacity of hard disks without increasing their physical size.

Researchers study interactions in molecules using AI

Researchers from the University of Luxembourg, Technische Universität Berlin, and the Fritz Haber Institute of the Max Planck Society have combined machine learning and quantum mechanics to predict the dynamics and atomic interactions in molecules. The new approach allows for a degree of precision and efficiency that has never been achieved before.

Pushing the (extra cold) frontiers of superconducting science

Scientists have developed a method to measure magnetic properties of superconducting and magnetic materials that exhibit unusual quantum behavior at very low temperatures in high magnetic fields.

NASA’s 2018 International Space Apps Challenge Returns to Huntsville

NASA’s 2018 International Space Apps Challenge is returning to Huntsville, Alabama, for a second year Oct. 19-21. The global hackathon brings together people of all ages and backgrounds to solve real-world problems with collaborative, innovation solutions during a 48-hour period.
