Exotic Quantum States: A New Research Approach
October 3, 2011 — Theoretical physicists have formulated a new concept to engineer exotic, so-called topological states of matter in quantum mechanical many-body systems. They linked concepts of quantum optics and ... > full story -
Researchers Realize High-Power, Narrowband Terahertz Source at Room Temperature
September 30, 2011 — Researchers 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 ... > full story -
Closing of a Collider . . . and Opening of a New Frontier: Fermilab Moves Toward New Discoveries
September 30, 2011 — Today, Fermi National Accelerator Laboratory (Fermilab) will shut down its Tevatron particle accelerator after nearly 30 years in operation. Named one of the top engineering achievements of the past ... > full story -
Physicists Consider Their Own Carbon Footprint
September 29, 2011 — An astrophysicist calls on physicists to pull their weight when it comes to climate change, drawing on his own research showing that astronomers average 23,000 air miles per year flying to ... > full story -
Technique to Control Light from Nanoparticles
September 29, 2011 — Chemists have discovered a way to use liquid crystals to control light scattered from gold nanorods. The researchers use voltage to sensitively manipulate the alignment of liquid crystal molecules ... > full story -
Single Ions -- Extremely Cool: Single Magnesium Ion Brought to a Standstill by Means of Novel, Simple Laser Cooling
September 29, 2011 — One of the fundamental questions in the search for the "theory of everything" is whether fundamental constants possibly vary. To prove this in the case of the fine-structure constant, for instance, ... > full story -
Redefining the Kilogram and the Ampere
September 29, 2011 — 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 Système Internationale ... > full story -
Matter Shows Abrupt Escape from Flatness: Lead Made to Undergo a Rapid Transition from 'Pancake' to Hemisphere
September 28, 2011 — At first glance, it seems as if billions of lead atoms have mysteriously disappeared. When exposed to heat, a layer of lead coated onto a nickel surface becomes almost invisible from one moment to ... > full story -
CERN Sets Course for Extra-Low-Energy Antiprotons
September 28, 2011 — The kick-off meeting for ELENA, the Extra Low Energy Antiproton Ring, has begun at CERN . Approved by CERN Council in June this year, ELENA is scheduled to deliver its first antiprotons in ... > full story -
Light from Galaxy Clusters Confirms General Theory of Relativity
September 28, 2011 — All observations in astronomy are based on light (electromagnetic radiation) emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. ... > full story
