Deborah Jin and Jun Ye are Highly Cited Researchers for 2015, according to the Thomas Reuters website. The website states, "Highly Cited Researchers 2015 represents some of world’s most influential scientific minds. About three thousand researchers earned this distinction by writing the greatest number of reports officially designated by Essential Science Indicators as Highly Cited Papers—ranking among the top 1% most cited for their subject field and year of publication, earning them the mark of exceptional impact."

JILA researchers garnered two Outstanding Presentation awards at the Boulder Laboratories 10th annual  Postdoctoral Poster Symposium held on July 17, 2013. Bryce Gadway, a research associate in the Ye group, was recognized for his presentation “Realizing a Lattice Spin System with Ultracold Polar Molecules.” Gadway’s co-authors included poster co-presenter Jacob Covey as well as Bo Yan, Steve Moses, Kaden Hazzard, Ana Maria Rey, Deborah Jin, and Jun Ye. Covey was cited for doing a commendable job as a presenter.

Last year the Ye group conducted an actual laboratory astrophysics experiment. Graduate students Brian Sawyer, Ben Stuhl, and Mark Yeo, research associate Dajun Wang, and Fellow Jun Ye fired cold hydroxyl (OH) radicals into a linear decelerator equipped with an array of highly charged electrodes and slowed the OH molecules to a standstill.

November 30, 2006: New CU-NIST Optical Atomic Clock Demonstrates Most Precise Ticks Ever

Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at the National Institute of Standards and Technology and the University of Colorado at Boulder have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock.

The Top Physics Stories for 2005

At the Relativistic Heavy Ion Collider (RHIC) on Long Island, the four large detector groups agreed, for the first time, on a consensus interpretation of several year’s worth of high-energy ion collisions: the fireball made in these collisions -- a sort of stand-in for the primordial universe only a few microseconds after the big bang -- was not a gas of weakly interacting quarks and gluons as earlier expected, but something more like a liquid of strongly interacting quarks and gluons (PNU 728).

June 29, 2005: Inside Science Research - Physics News Update - Ultraviolet Frequency Comb

Physicists at JILA, the joint institute of NIST and the University of Colorado, have created a new optical process to extend the production of coherent radiation into the extreme ultraviolet region of the electromagnetic spectrum. This process takes advantage of the fact that ultrafast laser pulses of femtosecond widths, separated by nanoseconds, manifest themselves as a superposition of light at different frequencies over a wide spectral band. 

June 02, 2005: Scientists find tiny new ways to measure up - The Christian Science Monitor

We've come a long way from the days when the length of the king's forearm was used to determine an object's size. Then, it was called the cubit, but the succession of short- and long-limbed kings made uniformity difficult. More modern standardized measures have helped. But these days, even those aren't enough. That's why the agency that sets measurement standards for the United States - the National Institute of Standards and Technology - is asking American technologists to assess the needs for new ones. With 80 percent of world trade dependent on such standards, NIST wants to be up to speed.

May 18, 2005: World's First UV 'Ruler' Sizes Up Atomic World

The world's most accurate "ruler" made with extreme ultraviolet light has been built and demonstrated with ultrafast laser pulses by scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder.
