Scientists Demonstrate Experimentally that SmB6 is a Topological Insulator

July 30, 2014

0 Comments

An international team of scientists has demonstrated experimentally, for the first time, that SmB6 is indeed a topological insulator. Spintronics is an emerging field of electronics, where devices work by manipulating the spin of electrons rather than the current generated by their motion. This field can offer significant advantages to computer technology. Controlling electron spin […]

Physicists Measure Magnetic Interactions between Single Electrons

July 28, 2014

1 Comment

By using a technique that binds two electrons together so that their spins point in opposite directions, physicists at the Weizmann Institute of Science were able to measure magnetic interactions between single electrons. Imagine trying to measure a tennis ball that bounces wildly, every time to a distance a million times its own size. The […]

Researchers Eliminate HIV from Cultured Human Cells for First Time

July 28, 2014

1 Comment

In a newly published study, researchers from Temple University detail how they created molecular tools to eliminate HIV from cultured human cells for first time. The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims’ DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent […]

Supercomputer Simulations Open the Door for Numerical Modeling of Nuclear Interactions

July 25, 2014

1 Comment

Researchers from RIKEN detail the first supercomputer simulations of ‘spin–orbit’ forces between neutrons and protons in an atomic nucleus, opening the door for numerical modeling of nuclear interactions. Protons and neutrons are held together at the center of an atom by powerful nuclear forces. A theory that can describe the interaction between just two of […]

Scientists Develop Membrane that Responds to Solvent Vapor

July 23, 2014

1 Comment

Material scientists have produced a membrane that curls very quickly when it comes into contact with the vapor from organic solvents, imitating biological structures which respond to an external stimulus like the Venus flytrap. An artificial skin now presented by a team working with scientists from the Max Planck Institute of Colloids and Interfaces in […]

Is the Universe a Bubble? – Physicists Work on the Multiverse Hypothesis

July 21, 2014

1 Comment

In several new studies and a short video, researchers from the Perimeter Institute for Theoretical Physics detail their work on the multiverse hypothesis. Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never […]

ATLAS Collaboration Detects Process Even Rarer Than Higgs Particle

July 17, 2014

1 Comment

A new published study from the ATLAS Collaboration reports the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles. Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world’s largest and most powerful “atom smasher,” […]

Chelyabinsk Meteorite Sheds New Light on Dinosaur Extinction

July 17, 2014

0 Comments

New measurements on the Chelyabinsk meteorite rule out the possibility for the Baptistina Asteroid Family being the source of the K/T impactor. Tucson, Arizonia — A long-standing debate about the source of the asteroid that impacted the Earth and caused the extinction of the dinosaurs has been put to rest thanks to the Chelyabinsk meteorite […]

Scientists Demonstrate a Photonic Router for the First Time

July 15, 2014

0 Comments

Scientists from the Weizmann Institute of Science have taken another step forward toward building quantum computers, demonstrating a photonic router for the first time. Weizmann Institute scientists have demonstrated for the first time a photonic router – a quantum device based on a single atom that enables routing of single photons by single photons. This […]

First Experimental Evidence of Boron “Buckyball”

July 14, 2014

0 Comments

An international team of researchers has shown that boron, carbon’s neighbor on the periodic table, can form a cage-like molecule similar to the buckyball. Providence, Rhode Island (Brown University) — The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a […]

Physicists Track Quantum Errors in Real Time

July 14, 2014

0 Comments

A team of scientists has tackled the first step in quantum error correction, successfully identifying errors as they happen in real time. Scientists at Yale University have demonstrated the ability to track real quantum errors as they occur, a major step in the development of reliable quantum computers. They report their results in the journal […]

Researchers Demonstrate the Scalability of Quantum Dot Architectures

July 11, 2014

0 Comments

New research from the RIKEN Center for Emergent Matter Science reveals how arrays of electrons trapped in nanoscale circuitry could form the basis for future scalable quantum computers. A single electron trapped in a semiconductor nanostructure can form the most basic of building blocks for a quantum computer. Before practical quantum computers can be realized, […]
