Astronomers Find Arsenic And Selenium In Milky Way's Halo
2012-04-30 09:27:50

The Big Bang produced lots of hydrogen and helium and a smidgen of lithium. All heavier elements found on the periodic table have been produced by stars over the last 13.7 billion years. Astronomers analyze starlight to determine the chemical makeup of stars, the origin of the elements, the ages of stars, and the evolution of galaxies and the universe. Now for the first time, astronomers have detected the presence of arsenic and selenium, neighboring elements near the middle of the periodic...

New Technique Efficiently Creates Single Photons For Quantum Information Processing
2012-04-23 04:48:52

Atomic blockade Using lasers to excite just one atom from a cloud of ultra-cold rubidium gas, physicists have developed a new way to rapidly and efficiently create single photons for potential use in optical quantum information processing — and in the study of dynamics and disorder in certain physical systems. The technique takes advantage of the unique properties of atoms that have one or more electrons excited to a condition of near-ionization known as the Rydberg state. Atoms...

Electron microscopy, conducted as part of the Shared Research Equipment (ShaRE) User Program at the Department of Energy's Oak Ridge National Laboratory, has led to a new theory to explain intriguing properties in a material with potential applications in capacitors and actuators. A research team led by ORNL's Albina Borisevich examined thin films of bismuth samarium ferrite, known as BSFO, which exhibits unusual physical properties near its transition from one phase to another. BSFO holds...

Study Finds Way To Observe Ion Responsible For Early Star Formation
2012-04-14 06:02:08

Researchers from the University of Arizona (UA) claim that they have found a way to observe the triatomic hydrogen ion believed to be the key element responsible for the formation of the first stars following the Big Bang. According to an article published to the UA News website on Wednesday, the molecule, which is known as H3+, is an ion that consists of three hydrogen atoms with just a pair of electrons to share between them, giving it a positive charge. It is believed to be the catalyst...

Quantum Network Created Based On Interfaces Between Single Atoms And Photons
2012-04-12 09:37:30

Brett Smith for Redorbit.com Quantum physicists have made a leap forward in subatomic particle communication by connecting two separate labs 21-meters apart using two atoms and a photon, according to a report published in the April 12 issue of Nature. A group from the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany said they have demonstrated the ability to construct a basic two-node network that could be expanded because of its high efficiency and fidelity....

JILA Team Demonstrates 'A New Way of Lasing': A 'Superradiant' Laser
2012-04-06 03:23:58

[ Watch the Video ] Physicists at JILA have demonstrated a novel “superradiant” laser design, which has the potential to be 100 to 1,000 times more stable than the best conventional visible lasers. This type of laser could boost the performance of the most advanced atomic clocks and related technologies, such as communications and navigation systems as well as space-based astronomical instruments. Described in the April 5, 2012, issue of Nature,* the JILA laser prototype...

New work suggests constructing novel particle opens the door to taming the mysteries of quantum tunneling Scientists at the Cavendish Laboratory in Cambridge have used light to help push electrons through a classically impenetrable barrier. While quantum tunneling is at the heart of the peculiar wave nature of particles, this is the first time that it has been controlled by light. Their research is published today, 05 April, in the journal Science. Particles cannot normally pass through...

World’s Most Sensitive Nanomechanical Sensor Revealed
2012-04-04 12:22:20

A team of physicists in Barcelona, Spain have for the first time fabricated and tested the world´s most sensitive Nanomechanical sensor, capable of detecting changes in mass of 1.7 yoctograms -- roughly the mass of a single proton. Team leader Professor Adrian Bachtold, of Catalan Institute of Technology´s Quantum NanoElectronics Group, and colleagues used the sensor, which is similar to a guitar string vibrating at very high frequencies (2 GHz), to compare the resonating...

New Isotope Measurement Could Alter History Of Early Solar System
2012-04-04 03:24:53

The early days of our solar system might look quite different than previously thought, according to research at the U.S. Department of Energy´s (DOE) Argonne National Laboratory published in Science. The study used more sensitive instruments to find a different half-life for samarium, one of the isotopes used to chart the evolution of the solar system. “It shrinks the chronology of early events in the solar system, like the formation of planets, into a shorter time span,”...
