Sentences with phrase «quantum gas»

The new 3 - D quantum gas clock uses additional lasers to trap atoms along three axes so that the atoms are held in a cubic arrangement.

«3 - D quantum gas atomic clock offers new dimensions in measurement.»

JILA's three - dimensional (3 - D) quantum gas atomic clock consists of a grid of light formed by three pairs of laser beams.

For a Fermi quantum gas under this clock's operating conditions, quantum mechanics favors a configuration where each individual lattice site is occupied by only one atom, which prevents the frequency shifts induced by atomic interactions in the 1 - D version of the clock.

In contrast, the new cubic quantum gas clock uses a globally interacting collection of atoms to constrain collisions and improve measurements.

He carried out his research in the Laboratoire Kastler Brossel with 1997 Nobel Prize co-recipient Claude Cohen - Tannoudji, this time studying the hydrodynamics of ultracold quantum gases.

The experimental data show the 3 - D quantum gas clock achieved a precision of just 3.5 parts error in 10 quintillion (1 followed by 19 zeros) in about 2 hours, making it the first atomic clock to ever reach that threshold (19 zeros).

(The acronym comes from the German for «quantum gases under weightlessness.»)

With so many atoms completely immobilized in place, JILA's cubic quantum gas clock sets a record for a value called «quality factor» and the resulting measurement precision.

Compared with Ye's previous 1 - D clocks, the new 3 - D quantum gas clock can reach the same level of precision more than 20 times faster due to the large number of atoms and longer coherence times.

First author Farina Kindermann and Professor Artur Widera in front of a quantum gas experimental setup for investigations on single atoms.

The authors believe that the first applications of the discovered binding mechanism might be in the area of cooling of atomic quantum gases.

A new technique that inhibits the reaction makes it possible to study certain properties of a quantum gas

In doing so, they are the first to harness the ultra-controlled behavior of a so - called «quantum gas» to make a practical measurement device.

The clock's centerpiece is an unusual state of matter called a degenerate Fermi gas (a quantum gas for Fermi particles), first created in 1999 by Ye's late colleague Deborah Jin.

The researchers use a quantum gas microscope to image the atoms, which have been cooled to a fraction of a degree above absolute zero and trapped in place using lasers.

«The most important potential of the 3 - D quantum gas clock is the ability to scale up the atom numbers, which will lead to a huge gain in stability,» Ye said.

The experiment showed remarkable results: When the external conditions on the chip were changed abruptly, the quantum gas could take on different temperatures at once.

The use of a quantum gas enables all of the atoms» properties to be quantized, or restricted to specific values, for the first time.

«This new strontium clock using a quantum gas is an early and astounding success in the practical application of the «new quantum revolution,» sometimes called «quantum 2.0»,» said Thomas O'Brian, chief of the NIST Quantum Physics Division and Ye's supervisor.
