JILA Researchers have generated the most powerful XUV frequency comb yet. This tabletop experiment generates powers comparable to synchrotron light sources’, while maintaining stability and control. This tool could light a second revolution in quantum physics by enabling spectroscopy at unprecedented precisions.
With the advent of... read more -->
We all know what a tenth of a second feels like. It’s a jiffy, a snap of the fingers, or a camera shutter click. But what does 14 billion years, which is the age of the universe, feel like?
JILA’s atomic clock has the precision to measure the age of the universe to within a tenth of a second. That sort of precision is difficult to intuit. Yet JILA’s atomic clock, which is the most... read more -->
JILA Fellow Jun Ye was named the 2018 winner of the I. I. Rabi Award by the IEEE Frequency Control Symposium. Ye was recognized “for the development of stabile, reproducible, and accurate atomic clocks based on optical lattices, and the use of those clocks to probe fundamental atomic interactions and quantum many-body systems.”
The award recognizes Ye’s sustained leadership in... read more -->
The reaction, at first glance, seems simple. Combustion engines, such as those in your car, form carbon monoxide (CO). Sunlight converts atmospheric water into a highly reactive hydroxyl radical (OH). And when CO and OH meet, one byproduct is carbon dioxide (CO2) – a main contributor to air pollution and climate change.
But it’s more complicated than that. Before CO2... read more -->
The Chinese Academy of Sciences announced on November 29, 2017 the election of JILA Fellow Jun Ye as a Foreign Member, China’s highest honor for foreign scientists:
The Chinese Academy of Sciences (CAS) promotes scientific and technological advances across the world. CAS includes a network of more than 100... read more -->
JILA and NIST Fellow Jun Ye was named the 2017 winner of the NIST Jacob Rabinow Applied Research Award, one of the top honors for the more than 1,600 scientific and technical NIST employees.
Jacob Rabinow was a prolific innovator working at the National Bureau of Standards (NBS), the predecessor... read more -->
JILA Fellows Jun Ye and Deborah Jin (1968 to 2016) have been named Highly Cited Researchers for 2017 by Clarivate Analytics (formerly Thomson Reuters).
The list of Highly Cited Researchers, published annually since 2014, recognizes scientists across the world with the greatest number (top 1%) of highly cited publications. The 2017 list covers the period from 2006 through 2016, and... read more -->
Marissa Weichman, a postdoc in the Ye group, has won the 2018 Justin Jankunas Doctoral Dissertation Award in Chemical Physics.
The award recognizes Weichman’s dissertation study of slow photoelectron velocity-map imaging of cryo-cooled anions. This spectroscopy technique can be used to study the detailed vibrational and electronic structure of exotic neutral species, including radicals... read more -->
JILA graduate student Sarah Bromley won the Harry Lustig Award from the American Physical Society Four Corners Meeting.
The Harry Lustig Award was established in 2015 to remember Lustig's academic achievements and strong commitment to support the work of physics students through APS. The award recognizes outstanding graduate-level research by individuals working in one of the four... read more -->
Why are we here? This is an age-old philosophical question. However, physicists like Will Cairncross, Dan Gresh and their advisors Eric Cornell and Jun Ye actually want to figure out out why people like us exist at all. If there had been the same amount of matter and antimatter created in the Big Bang, the future of stars, galaxies, our Solar System, and life would have disappeared in a flash... read more -->
Imagine A Future . . . The International Moon Station team is busy on the Moon’s surface using sensitive detectors of gravity and magnetic and electric fields looking for underground water-rich materials, iron-containing ores, and other raw materials required for building a year-round Moon station. The station’s mission: launching colonists and supplies to Mars for... read more -->
Researchers at JILA and around the world are starting a grand adventure of precisely controlling the internal and external quantum states of ultracold molecules after years of intense experimental and theoretical study. Such control of small molecules, which are the most complex quantum systems that can currently be completely understood from the principles of quantum mechanics, will allow... read more -->
Leah Dodson won the Miller Prize at the 72nd International Symposium on Molecular Spectroscopy, held June 19–23 in Urbana, Illinois. Dodson is an NRC postdoc whose official advisor is Jun Ye, but who primarily works on molecular spectroscopy in the Mathias Weber lab. Her award-winning talk was entitled “Oxalate Formation in Titanium––Carbon Dioxide Anionic Clusters Studied by Infrared... read more -->
Bryce Bjork’s talk entitled “Direct Measurement of OD+CO-> cis-DOCO, trans-DOCO, and D+CO2 Branching Kinetics using Time-Resolved Frequency Comb Spectroscopy” was selected by a panel of judges at the International Symposium on Molecular Spectroscopy as one of three winners of the 2017 Rao Prize. The prize... read more -->
Research associate Shimon Kolkowitz and his colleagues in the Ye group and Rey theory group have developed a powerful new way to experimentally simulate the complex behavior of electrons in solids. In these experiments, the team uses its strontium lattice optical clock not to track time, but to take advantage of the ultracold atoms in the clock mimicking the quantum behavior of electrons in a... read more -->
Deborah Jin, Jun Ye, and their students wrote a review during the summer of 2016 for Nature Physics highlighting the accomplishments and future directions of the relatively new field of ultracold-molecule research. The field was pioneered by the group’s creation of the world’s first gas of ultracold potassium-rubidium (KRb) molecules in 2008.
The molecules were made by first... read more -->
Bryce Bjork, Thinh Bui and colleagues use cavity-enhanced frequency comb spectroscopy to monitor in real time important chemical reaction kinetices of OH + CO. For the first time, they have detected the short-lived elusive intermediate HOCO under ambient conditions.
