Strontium atomic clock demonstrates super-fine 'ticks'
11-30-2006 · EurekAlert!Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at JILA (a joint institute of NIST and the University of Colorado at Boulder) have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock—techniques that may be useful in time keeping, precision measurements of high frequencies, and quantum computers using neutral atoms as bits of information.

- Optical Atomic Clock: A long look at the captured atoms
02-05-2008 · EurekAlert!
In the case of one of the candidates for an optical clock which is developed at Physikalisch-Technische Bundesanstalt, an optical grating clock with strontium atoms, the loading of cold atoms into an optical grating has been optimized to such an extent that approx. 106 strontium atoms are loaded into the grating within 150 milliseconds at a temperature of a few microkelvin. There, the atoms remain stored for over one second and are available for a precision measurement of the optical frequency.

- Atomic clock signals may be best shared by fiber-optics
03-02-2007 · EurekAlert!
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS), but today's best atomic clocks are so accurate that more stable methods are needed. The best solution may be to use lasers to transfer data over fiber-optic cables, according to scientists at JILA.

- NIST announces first observation of 'persistent flow' in a gas
11-27-2007 · EurekAlert!
Using laser light to stir an ultracold gas of atoms, researchers at NIST and the Joint Quantum Institute have demonstrated the first 'persistent' current in an ultracold atomic gas, a frictionless flow of particles. This form of superfluidity, might help bring to the surface some deep physics insights, and enable super-sensitive rotation sensors that could someday make navigation more precise.

- Doomsday clock moves forward 2 minutes
01-17-2007 · EurekAlert!
The Bulletin of the Atomic Scientists (BAS) is moving the minute hand of the Doomsday Clock on January 17, 2007, from seven to five minutes to midnight. Reflecting global failures to solve the problems posed by nuclear weapons and the climate crisis, the decision by the BAS Board of Directors was made in consultation with the Bulletin's Board of Sponsors, which includes 18 Nobel Laureates.

- Virtual duck bills demonstrate species coexistence
02-26-2007 · EurekAlert!
How do species coexist rather than outcompete? The classical explanation is that each species has evolved morphological traits that allow it to exploit different resources more efficiently, but direct evidence is rare. Using dabbling ducks, like the mallard, which are primarily filter feeders, Gurd demonstrates that different lengths of lamellae -- the comb-like projections on the bill that sieve food particles from pond water -- allow duck species to coexist.

- Clock comparison yields clues to 'constant' change
02-15-2007 · EurekAlert!
Years of comparisons among the world's best atomic clocks -- based on different atoms -- have established the most precise limits ever achieved in the laboratory for detecting possible changes in so-called 'constants' of nature. The comparisons at NIST may help scientists test the latest theories in physics and develop a more complete understanding of the history of the universe.

- New method to directly probe the quantum collisions of individual atoms
04-18-2007 · EurekAlert!
A new method has been developed to directly and precisely measure a quantum property of individual atoms -- the phase shifts that result when they collide at ultracold temperatures -- in a way that is independent of the accuracy-limiting density of the atoms. These shifts, which had been impossible to measure with high precision, are important for atomic clocks and other areas of contemporary atomic physics, including research on super-sensitive atom lasers high-temperature superconductivity.
