Trapping Atoms, Not Space Ships, with Tractor Beams

University of Adelaide researchers have delved into the realm of Star Wars and created a powerful tractor beam – or light-driven energy trap – for atoms. Rather...
magnetic fields

Discovering a Previously Unknown Role for a Source of Magnetic Fields

Magnetic forces ripple throughout the universe, from the fields surrounding planets to the gasses filling galaxies, and can be launched by a phenomenon called...
neurodegenerative diseases

Researchers Model How Toxic Proteins Course Through the Brain, Lead to...

Many neurodegenerative diseases spread by hijacking the brain’s connective circuitry to transport toxic proteins, which gradually accumulate and trigger symptoms of dementias. Now, researchers...
superfluidity

Disrupting Crystalline Order to Restore Superfluidity

Theoretical and experimental scientists at the Universität Hamburg have together observed light induced superfluidity. The team of scientists led by Prof. Ludwig Mathey and...
nanostructuring

Hot Aluminum Etches Smooth Nano-Holes in Semiconductors

A German-French research team has identified surprising properties of nano-holes in semiconductor materials produced by a promising technique: In their experiments, hot aluminum droplets...
magnetic semiconducting

Graphene Controls Surface Magnetism at Room Temperature

In a refreshing change of perspective, theoretical physicist Dr Zeila Zanolli has looked at the proximity effects of graphene on a magnetic semiconducting substrate,...
wind farms

Windier Windfarms

You’ve probably seen them, perhaps on long roadtrips: wind turbines with enormous, hypnotic rolling blades, harnessing the clean power of wind for conversion into...
Transition metal dichalcogenides

Transition Metal Dichalcogenides Could Increase Computer Speed, Memory

Transition metal dichalcogenides (TMDCs) possess optical properties that could be used to make computers run a million times faster and store information a million...
Nuclear Pasta

Nuclear Pasta, the Hardest Known Substance in the Universe

A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the...
superconductor synapse

Modified Superconductor Synapse Reveals Exotic Electron Behavior

Electrons tend to avoid one another as they go about their business carrying current. But certain devices, cooled to near zero temperature, can coax...
Protein Transport

Pile-Ups in Protein Transport

Anyone who has ever tried to find a way through a crowded pedestrian zone has – literally – run into the problem: While some...
optical parametric oscillator

Experiment Obtains Entanglement of Six Light Waves with a Single Laser

Austrian physicist Erwin Schrödinger (1887-1961), one of the giants of contemporary science, considered “entanglement” the most interesting property in quantum mechanics. In his view,...
optical device

Fish-Eye Lens May Entangle Pairs of Atoms

Nearly 150 years ago, the physicist James Maxwell proposed that a circular lens that is thickest at its center, and that gradually thins out...
Tantalum disulfide

Atoms and Electrons Watched at Work

The properties of materials are determined by their atomic structure. If atoms and electrons change their arrangement, the characteristics of a material also change. The complex...
Quantum Simulation

Quantum Simulation Reveals Mobility Edge in a Low-Dimensional Disordered Landscape

A recent flood of research scholarship on electronic transport in low-dimensional (2D or 1D) materials like graphene or carbon nanotubes reflects the tremendous potential...

UT-ORNLTeam Makes First Particle Accelerator Beam Measurement in Six Dimensions

The first full characterization measurement of an accelerator beam in six dimensions will advance the understanding and performance of current and planned accelerators around...
plasma accelerator

World Record – Low-Draft Electron Bunches Drive High Plasma Wakes

Scientists at DESY have achieved a milestone towards the usability of novel, plasma-based particle accelerators. Using the electron beam of the PITZ accelerator, the Photo Injector...
intense lasers

Surprise Slow Electrons Are Produced When Intense Lasers Hit Clusters of...

Intense laser cluster interactions occur when small clusters of atoms, nanometres (billionths of a metre) in size, are struck with intense lasers. This happens,...
electronic hotspots

Researchers Put a New Spin on Cooling Electronic Hotspots

The longevity of electronic devices is tested in many ways as they endure the rigors of daily usage. Even when they are treated with...
