  • Ye at JILA
    Around 150 promising inventions are generated annually within the 抖阴传媒在线. To support these inventions, the聽Venture Partners at CU 抖阴传媒在线 organization established the聽Embark Deep Tech Startup Creator, an accelerator program for start-up companies coming out of CU 抖阴传媒在线. This year, Venture Partners at CU 抖阴传媒在线 announced the聽Embark Entrepreneurs in Residence cohort. This cohort pairs entrepreneurs with promising inventions.

    In the case of JILA, entrepreneur Eva Yao will lead FLARI in bringing to market a breathalyzer capable of detecting molecules in breath or air samples invented by Jun Ye for fast detection of diseases and contaminants.
  • An artistic representation of a "hot carrier" gold nanoparticle
    In a new ACS Nano paper, JILA and NIST Fellow David Nesbitt, along with former graduate student Jacob Pettine and other collaborators, developed a new method for measuring the dynamics of specific particles known as 鈥渉ot carriers,鈥 as a function of both time and energy, unveiling detailed information that can be used to improve collection efficiencies.
  • The near-universal ability of EDTA to accommodate metal cations comes from its molecular flexibility, which allows it to respond to the chemical nature of the metal ion it binds.
    To understand how EDTA binds to metal ions and water molecules, Madison Foreman, a former JILA graduate student in the Weber group, now a postdoctoral researcher at the University of California, Berkeley, Terry, and their supervisor, JILA Fellow J. Mathias Weber, studied the geometry of the EDTA binding site using a unique method that helped to isolate the molecules and their bound ions, allowing for more in-depth analyses of the binding interactions. They published a series of three papers on this topic. In their first paper, published in the Journal of Physical Chemistry A, they found that the size of the metal ion changes where it sits in the EDTA binding site, which affects other binding interactions, especially with water.

    Colorado 9News recently interviewed JILA Fellow and 抖阴传媒在线 physics professor Heather Lewandowski as she discussed a recent paper with over 1,000 authors. This recent paper, published in the聽Astrophysical Journal,聽focused on solving the mystery of the Sun's corona, a ring of significantly hotter temperatures surrounding the Sun compared to its core. Lewandowski recruited over 1,000 undergraduate students as researchers to study this phenomenon as they analyzed data from observations of the corona. The entire project took multiple years and culminated in over 56,000 hours of research.聽In the 9News interview, Lewandowski stated: "It's really important for us to understand our Sun because it has a large impact on Earth."
  • JILA and NIST Fellow Ana Maria Rey

It provides recipients substantial financial support over five years, allowing them to pursue innovative and high-impact research endeavors.
  • The most precise measurement yet of eEDM using electrons confined within HfF+ molecular ions.
    Some of the biggest questions about our universe may be solved by scientists using its tiniest particles. Since the 1960s, physicists have been looking at particle interactions to understand an observed imbalance of matter and antimatter in the universe. Much of the work has focused on interactions that violate charge and parity (CP) symmetry. This symmetry refers to a lack of change in our universe if all particles鈥 charges and orientations were inverted. 鈥淭his charge and parity symmetry is the symmetry that high-energy physicists say needs to be violated to result in this imbalance between matter and antimatter,鈥 explained JILA research associate Luke Caldwell. To try to find evidence of this violation of CP symmetry, JILA and NIST Fellows Jun Ye and Eric Cornell, and their teams, including Caldwell, collaborated to measure the electron electric dipole moment (eEDM), which is often used as a proxy measure for the CP symmetry violation. The eEDM is an asymmetric distortion of the electron鈥檚 charge distribution along the axis of its spin. To try to measure this distortion, the researchers used a complex setup of lasers and a novel ion trap. Their results, published in Science聽as the cover story and Physical Review A, leveraged a longer experiment time to improve the precision measurement by a factor of 2.4, setting new records.
  • JILA graduate student Alexander Aeppli stands next to the strontium atomic clock in JILA and NIST Fellow Jun Ye's laboratory
    JILA graduate student Alexander Aeppli is one of a team of researchers working on the world鈥檚 most precise clocks. In the laboratory of JILA and NIST Fellow Jun Ye, Aeppli focuses on improving the strontium atomic clock using powerful ultrastable lasers. 鈥淭he laser drives an electronic transition in strontium,鈥 Aeppli explained. 鈥淎nd we want to make sure the transition within the strontium is exact.鈥 Before the transition occurs, the strontium atoms are trapped within an optical lattice inside the clock. Once trapped, the strontium atoms can transition when exposed to a particular color (or frequency) of light, and the researchers, like Aeppli, measure this transition frequency as a form of timekeeping. The frequency can then be used as the precise standard of time worldwide.
  • An artistic rendering of the bacterium's riboswitch and its interactions with three different potential ligands.
    To better understand the dynamics of aptamer and ligand binding, Marton Menendez, along with JILA and NIST Fellow David Nesbitt, looked at the lysine (an amino acid) riboswitch in Bacillus subtilis, a common type of bacterium present in environments ranging from cow stomachs to deep sea hydrothermal vents. With this model organism, the researchers studied how different secondary ligands, like, potassium, cesium, and sodium, affect riboswitch activation, or its physical folding.
  • A representation of bosonic pair creation, which creates an entangled state between atoms
    A new approach recently described in Physical Review Letters explores a new way to generate squeezing that is exponentially faster than previous experiments and generates a new flavor of entanglement: two-mode squeezing鈥攁 type of entanglement that is thought to be used for improving the best atomic clocks and for sensing how gravity changes the flow of time. This promising new approach was developed by a collaboration of JILA and NIST Fellows Ana Maria Rey and James K. Thompson, and their team members, along with Bhuvanesh Sundar, a former postdoctoral researcher at JILA now at Rigetti Computing, and former JILA research associate Dr. Robert Lewis-Swan, now an Assistant Professor at the University of Oklahoma.
