Max-Planck-Institute of Quantum Optics A team in the Laboratory for Attosecond Physics (LAP) at the Max-Planck-Institute of Quantum Optics has taken another step toward the achievement of complete control over the waveform of pulsed laser light. Together with colleagues based at LMU and the Technische Universität München (TUM), they have constructed a detector which provides a detailed picture of the waveforms of laser pulses that last for a few femtoseconds (1 fs = 10-15 seconds)....

Mastering the fine structuring of ultrashort light fields An expedition through the fast-paced microscopic world of atoms reveals electrons that spin at enormous speeds and the gigantic forces that act on them. Monitoring the ultrafast motion of these electrons requires ultrashort flashes of light. However, in order to control them, the structure of these light flashes, or light pulses, needs to be tamed as well. This type of control over light pulses has now been achieved, for the first...

A newly discovered magnetic phenomenon could accelerate data storage by several orders of magnitude. With a constantly growing flood of information, we are being inundated with increasing quantities of data, which we in turn want to process faster than ever. Oddly, the physical limit to the recording speed of magnetic storage media has remained largely unresearched. In experiments performed on the particle accelerator BESSY II of Helmholtz-Zentrum Berlin, Dutch researchers have now achieved...

Scientists develop a method to film nanostructures When we catch a cold, the immune system steps in to defend us. This is a well-known biological fact, but is difficult to observe directly. Processes at a molecular level are not only miniscule, they are often extremely fast, and therefore difficult to capture in action. Scientists at Helmholtz-Zentrum Berlin fr Materialien und Energie (HZB) and the Technische Uni-versität Berlin (TUB) now present a method that takes us a good step...

Air Force Office of Scientific Research-supported physicists at the University of California, Berkeley in collaboration with researchers from the Max Planck Institute of Quantum Optics and the U.S. Department of Energy's Lawrence Berkeley National Laboratory, became the first researchers to observe the motion of an atom's valence or outermost electrons in real-time by investigating the ejection of an electron from an atom by an intense laser pulse. In the experiments, an electron in a krypton...

At its most basic level, understanding chemistry means understanding what electrons are doing. Research published in The Journal of Chemical Physics not only maps the movement of electrons in real time but also observes a concerted electron and proton transfer that is quite different from any previously known phase transitions in the model crystal, ammonium sulfate. By extending X-ray powder diffraction into the femtosecond realm, the researchers were able to map the relocation of charges in...

Scientists at the National Research Council of Canada (NRC) and the University of Ottawa (uOttawa) enjoyed a bird's eye view of a chemical bond as it breaks. The making and breaking of chemical bonds underlie the biochemical processes of life itself. A greater understanding of the quantum processes that lead to chemical reactions may lead to new strategies in the design and control of molecules "” ultimately leading to scientific breakthroughs in health care and diagnostic medicine,...

Charting femtosecond energy flow could aid redesign of molecules to improve light capture University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize in Physiology or Medicine. The researchers' study of green fluorescent protein (GFP) and the structural changes it undergoes when it fluoresces is the cover story of the Nov. 12 issue of the journal...

The National Physical Laboratory (NPL) has helped to establish that femtosecond comb lasers can provide accurate measurement of absolute distance in formation flying space missions. NPL, along with collaborators, produced technical reports for the European Space Agency. The conclusions demonstrated that the lasers were a suitable method for measurement in such missions. Formation flying missions involve multiple spacecrafts flying between tens and hundreds of meters apart, which autonomously...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
