New blueprint for more stable quantum computers

Researchers at the Paul Scherrer Institute (PSI) have put forward a detailed plan of how faster and better defined quantum bits—qubits—can be created. The central elements are magnetic atoms from the class of so-called ...

The mystery of pointy oil droplets

A certain type of oil droplets changes shape when cooled and shrunk: from spherical through icosahedral to flat hexagonal. Two competing theories couldn't fully explain this, but now, a Physical Review Letter by Ireth García-Aguilar ...

Search for axions from nearby star Betelgeuse comes up empty

The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter—a ...

Scientists use diamonds to generate better accelerator beams

Beam-driven wakefield acceleration approaches are promising candidates for future large-scale machines, including X-ray free electron lasers and linear colliders, as they have the potential to improve efficiency and reduce ...

Lasers create miniature robots from bubbles

Robots are widely used to build cars, paint airplanes and sew clothing in factories, but the assembly of microscopic components, such as those for biomedical applications, has not yet been automated. Lasers could be the solution. ...

Innovations through hair-thin optical fibers

Scientists at the University of Bonn have built hair-thin optical fiber filters in a very simple way. They are not only extremely compact and stable, but also color-tunable. This means they can be used in quantum technology ...

Electrons caught in the act

A team of researchers from the Faculty of Pure and Applied Sciences at the University of Tsukuba filmed the ultrafast motion of electrons with sub-nanoscale spatial resolution. This work provides a powerful tool for studying ...

Two-photon polymerization of PEGda hydrogel microstructure

The fabrication of shape-memory hydrogel scaffolds not only requires biocompatibility, micrometer resolution, high mechanical strength, but also requires a low polymerisation threshold in high-water content environment to ...

Scientists gain an unprecedented view of irradiated nuclear fuel

In a feat requiring perseverance, world-leading technology, and no small amount of caution, scientists have used intense X-rays to inspect irradiated nuclear fuel. The imaging, led by researchers at Purdue University and ...

Storing information with light

New photo-ferroelectric materials allow storage of information in a non-volatile way using light stimulus. The idea is to create energy efficient memory devices with high performance and versatility to face current challenges. ...

Do simulations represent the real world at the atomic scale?

Computer simulations hold tremendous promise to accelerate the molecular engineering of green energy technologies, such as new systems for electrical energy storage and solar energy usage, as well as carbon dioxide capture ...

The long-range transport of deconfined magnetic hedgehogs

Spintronics is an emerging area of research that aims to develop devices that transmit, process and store information leveraging the intrinsic angular momentum of electrons, known as spin. A key objective of spintronics studies ...

Using drones to create local quantum networks

A team of researchers affiliated with several institutions in China has used drones to create a prototype of a small airborne quantum network. In their paper published in the journal Physical Review Letters, the researchers ...

New mathematical model: How dangerous bacteria form colonies

It can be observed every time you take a shower: Small droplets of water join together to form larger and larger drops—until they are so heavy that they run down the wall. Scientists call this daily-life phenomenon coalescence—which ...

Phase diagram for infinite layer nickel superconductors

NUS physicists have developed a method to induce the transition of a rare-earth nickelate from their native perovskite form to infinite-layer structures. This allowed them to build a complete phase diagram of this nickelate ...
