(PhysOrg.com) -- Theoretical physicists of the University of Innsbruck have formulated a new concept to engineer exotic, so-called topological states of matter in quantum mechanical many-body systems.

(PhysOrg.com) -- A thin sheet of plastic has been making headlines at Princeton as a magical flying carpet, after the publication of a paper describing experiments by the team with their prototype sheet of plastic that uses piezoelectric actuators and sensors to move.

Researchers at Northwestern University have developed a simpler way to generate single-chip terahertz radiation, a discovery that could soon allow for more rapid security screening, border protection, high sensitivity biological/chemical analysis, agricultural inspection, and astronomical applications.

A powerful US atom-smasher that was the world's biggest particle collider for nearly a quarter-century closed forever on Friday, solidifying Europe's place as the world leader in physics.

(PhysOrg.com) -- "A perplexing philosophical issue in science is the question of anticipation, or prediction, versus causality," Shawn Pethel tells PhysOrg.com.

Conductors of electrical current, including copper, heat up and limit the ability to increase circuit densities. Unusual materials that exhibit the so-called ‘quantum spin Hall effect’, in which current can flow without dissipating heat, could provide an alternative to conventional metals.

Molecular motion in proteins comes in three distinct classes, according to a collaboration by researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, in research reported in Physical Review Letters.

(PhysOrg.com) -- If typical black paint absorbs about 85% of incoming light, then a newly designed metamaterial that absorbs up to 99% of incoming light may be considered “darker than black." By taking advantage of the unique light-scattering properties of metamaterials, researchers have discovered that a hyperbolic metamaterial with a corrugated surface can have a very low reflectance, which could make it promising for high-efficiency solar cells, photodetectors, and radar stealth technology.

Perhaps one of Leonardo da Vinci's greatest paintings has never been reprinted in books of his art. Known as the "Battle of Anghiari," it was abandoned and then lost—until a determined Italian engineer gave the art world hope that it still existed, and a physicist from the U.S. Department of Energy's Argonne National Laboratory developed a technique that may reveal it to the world once again.

Quantum logic is quite a new and absolutely fascinating field of physics and might – ultimately – lead to the fabrication of a quantum computer. And it could also aid the search for the "theory of everything" – the missing link between traditional physics and quantum physics. One of the fundamental questions hereby is whether fundamental constants possibly vary.

The development of periodic structures in embryos giving rise to the formation of, e.g., spine segments, is controlled not by genes but by simple physical and chemical phenomena.

(PhysOrg.com) -- Neutron stars are what’s left over from supernova explosions; so dense that protons and electrons are crushed together forming neutrons. The result is something relatively small in size, but incredibly dense.

The kick-off meeting for ELENA, the Extra Low Energy Antiproton Ring, starts today at CERN. Approved by CERN Council in June this year, ELENA is scheduled to deliver its first antiprotons in 2016.

New research using graphene presents the most precise measurements of the quantum Hall effect ever made, one of the key steps in the process to redefine two SI units.

(AP) -- Aside from the slogan on the water tower that reads "City of Energy," there is little in this leafy Chicago suburb of gently rolling hills to indicate that it has been the center of the universe when it comes to studying, well - the universe.
