Physicists Measure Magnetic Interactions between Single Electrons

July 28, 2014

0 Comments

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 […]

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 […]

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,” […]

New Observations Reveal How Electrons Accelerate in the Van Allen Radiation Belts

July 16, 2014

0 Comments

Using new data from the Van Allen Probes, a newly published study reveals the first direct observation of two processes that, in a chain, cause the acceleration of electrons in Earth’s outer radiation belt. One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, […]

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 […]

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, […]

Solid-State Physicists Consider the ‘Anticrystal’

July 8, 2014

0 Comments

Physicists show that the anticrystal, a theoretical solid that is completely disordered, should undergird our understanding of most materials. For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and molecules make. Now physicists […]

The Reinterpretation of Cold Dark Matter as a Bose-Einstein Condensate

July 2, 2014

4 Comments

Newly published research signifies the reinterpretation of cold dark matter, opening up the possibility that it could be regarded as a very cold quantum fluid governing the formation of the structure of the Universe. Tom Broadhurst, an Ikerbasque researcher at the UPV/EHU’s Department of Theoretical Physics, has participated alongside scientists of the National Taiwan University […]

New Buckyball Research Will Aid Biological Studies

June 30, 2014

0 Comments

Using SLAC’s Linac Coherent Light Source X-ray laser, researchers take a closer look at soccer-ball-shaped carbon molecules called buckyballs. Scientists at SLAC have been blowing up “buckyballs” – soccer-ball-shaped carbon molecules – with an X-ray laser to understand how they fly apart. The results, they say, will aid biological studies by improving the analysis of […]

Three Closely Orbiting Supermassive Black Holes Could Help in the Search for Gravitational Waves

June 26, 2014

0 Comments

An international team of astronomers discovered three closely orbiting supermassive black holes that could help in the search for gravitational waves. An international team, including Oxford University scientists, led by Dr Roger Deane from the University of Cape Town, examined six systems thought to contain two supermassive black holes. The team found that one of […]
