Physicists set 'speed limit' for future superconducting magnet

02-11-2007 · EurekAlert!

The material currently used in magnetic resonance imaging machines -- a low-temperature superconducting alloy of niobium -- has been pushed almost as far as it can go, to around 21 Tesla. Now a team led Northwestern University researchers has identified a high-temperature superconductor -- called Bi-2212 -- as a material that might be suitable for the new wires needed to one day build the most powerful superconducting magnet in the world, a 30 Tesla magnet.

Light seems to defy its own speed limit
08-16-2007 · EurekAlert!
It's a speed record that is supposed to be impossible to break. Yet two physicists are now claiming they have propelled photons faster than the speed of light. This would be in direct violation of Einstein's special theory of relativity, which states that nothing, under any circumstance, can exceed the speed of light. Researchers from the University of Koblenz, German, say they have tunnelled photons "instantaneously" across a barrier of various sizes up to a meter wide.

Iowa State physicist leads team designing detector for international particle collider
04-13-2007 · EurekAlert!
John Hauptman, an Iowa State University professor of physics and astronomy, is leading an international team that's designing a detector for the proposed International Linear Collider. The collider would be about 19 miles long and accelerate electrons and positrons to nearly the speed of light. The particles would collide at the center of the machine at extremely high energies. Collider detectors would record those collisions. Physicists expect the collisions to create new particles and help them understand how the universe works.

Digital cable goes quantum
09-26-2007 · EurekAlert!
Physicists at the National Institute of Standards and Technology have transferred information between two 'artificial atoms' by way of electronic vibrations on a microfabricated aluminum cable, demonstrating a new component for potential ultra-powerful quantum computers of the future. The setup resembles a miniature version of a cable television transmission line, but with some powerful added features, including superconducting circuits with zero electrical resistance, and multitasking data bits that obey the unusual rules of quantum physics.

Nuclear physicists examine oxygen's limits
09-13-2007 · EurekAlert!
Physicists at the National Superconducting Cyclotron Laboratory at Michigan State University have made a unique measurement of an exotic oxygen nucleus, leading scientists one step closer to deciphering the behavior of the element at its limits of existence. The finding, published in Physical Review Letters, confirms a relatively new theoretical model that predicts dramatic changes in structure as one looks at heavier and heavier oxygen nuclei.

Racing Ahead at the Speed of Light
02-06-2008 · Brookhaven National Laboratory
Imagine trying to catch up to something moving close to the speed of light - the fastest anything can move - and sending ahead information in time to make mid-path flight corrections. Impossible? Not quite. Physicists at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator at Brookhaven Lab, have achieved this tricky task - and the results may save the Lab money and time in their quest to understand the inner workings of the early universe.

Physicists reveal water's secrets in journal 'Science'
03-02-2007 · EurekAlert!
Equipped with high-speed computers and the laws of physics, scientists from the University of Delaware and Radboud University in the Netherlands have developed a new method to "flush out" the hidden properties of water. The research is reported in Science. Their first-principle simulation of water molecules -- based exclusively on quantum physics laws -- has numerous applications, from biological investigations of protein folding and other life processes, to the design of the next generation of power plants.

Computer simulation predicts Voyager 2 will reach major milestone in space in late 2007-early 2008
11-27-2007 · EurekAlert!
Using a computer model simulation, Haruichi Washimi, a physicist at the University of California, Riverside, has predicted that the interplanetary spacecraft Voyager 2 will cross the "termination shock" -- a spherical shell around the solar system that marks where the solar wind slows down to subsonic speed -- in late 2007-early 2008.
