  • Tanya Ramond, the Founder and CEO of Sapienne Consulting
    While industry and academia tend to be the two main job trajectories after graduating with a Ph.D. or postdoctoral degree, some individuals, like Tanya Ramond, combine aspects of these careers in her role as Founder and CEO of Sapienne Consulting.

    鈥淎s an independent consultant, I am driven by a deep passion for commercialization and product strategy in deep tech areas,鈥� Ramond elaborates. 鈥淭hese areas of technology are particularly challenging, often hardware-based, and heavily reliant on intellectual property. My expertise and enthusiasm extend to fields like quantum physics, optics, aerospace, and clean tech, inspiring those around me to push the boundaries of what is possible.鈥�
  • (L to R): JILA Fellow and 麻豆免费版下载Boulder Physics professor Heather Lewandowski and NSF Director Dr. Sethuraman Panchanathan listen as JILA graduate student Qizhong Liang explains some of the quantum research happening at JILA.
    To highlight the pivotal role of federal funding in advancing quantum research, the National Science Foundation (NSF) hosted its inaugural Quantum Showcase on Capitol Hill two weeks ago. The event highlighted the potential of government-funded quantum initiatives and included NSF-funded quantum researchers nationwide. JILA, a joint institute between the 麻豆免费版下载 and NIST, was represented at the event by JILA Fellow and 麻豆免费版下载 Physics Professor Heather Lewandowski and JILA graduate student Qizhong Liang, a member of JILA and NIST Fellow Jun Ye鈥檚 research group.
  • Atoms in an optical lattice perform a "quantum walk" where they experience many different quantum phenomena, such as superposition or tunneling.
    JILA Fellow and NIST Physicist and 麻豆免费版下载 Physics Professor Adam Kaufman and his team, along with collaborators at NIST (the National Institute of Standards and Technology), have demonstrated a novel method of boson sampling using ultracold atoms (specifically, bosonic atoms) in a two-dimensional optical lattice of intersecting laser beams.
  • Atoms inside of an optical cavity exchange their momentum states by "playing catch" with photons. As the atoms absorb photons from an applied laser, the whole cloud of atoms recoil rather than the individual atoms.
    In a new paper published in Science, JILA and NIST Fellows Ana Maria Rey and James Thompson, JILA Fellow Murray Holland, and their teams proposed a way to overcome atomic recoil by demonstrating a new type of atomic interaction called momentum-exchange interaction, where atoms exchanged their momentums by exchanging corresponding photons.
  • Heising-Simons Foundation Awards $3 Million for Informing Gravity Theory
    The Heising-Simons Foundation's Science program has announced a generous grant of $3 million over three years, aimed at bolstering theoretical and experimental research efforts to bridge the realms of Atomic, Molecular, and Optical (AMO) physics with quantum gravity theories. Among the recipients, a notable grant was awarded to a multi-investigator collaboration spearheaded by the 麻豆免费版下载 (麻豆免费版下载Boulder) and JILA, a joint institute of 麻豆免费版下载Boulder and the National Institute of Standards and Technology (NIST).
  • Multilevel atoms on a superradiance potential "rollercoaster" inside an optical cavity. The system can be tuned to generate squeezing in a dark state where it will be immune to superradiance.
    Ana Maria Rey and her team discovered a method for how to not only create dark states in a cavity, but more importantly, make these states spin squeezed. Their findings could open remarkable opportunities for generating entangled clocks, which could push the frontier of quantum metrology in a fascinating way.
  • Atomic dipoles on a lattice interact to produce an observable spatially varying frequency shift (shown as blue to red).
    In a new study published in Science today, JILA and NIST (National Institute of Standards and Technology) Fellow聽and 麻豆免费版下载 physics professor Jun Ye and his research team have taken a significant step in understanding the intricate and collective light-atom interactions within atomic clocks, the most precise clocks in the universe.
  • Researchers observed the dynamic phases of BCS superconductor interactions in a Cavity QED by measuring the light leakage from the cavity.
    As a thermodynamic phase of matter, superconductors typically exist in an equilibrium state. But recently, researchers at JILA became interested in kicking these materials into excited states and exploring the ensuing dynamics. As reported in a new Nature paper, the theory and experiment teams of JILA and NIST Fellows Ana Maria Rey and James K. Thompson, in collaboration with Prof. Robert Lewis-Swan at the University of Oklahoma, simulated superconductivity under such excited conditions using an atom-cavity system.
  • A schematic of a laser going through an AOM, which sends sound waves into a silicon cavity.
    In a new Optica paper, Ye鈥檚 team, working with JILA electronic staff member Ivan Ryger and John "Jan" Hall, describe implementing a new approach for the PDH method, reducing RAM to never-before-seen minimal levels while simultaneously making the system more robust and simpler.
  • JILA graduate student Nick Jenkins adjusts a setting on his laser tabletop setup.
    Nick Jenkins, a graduate student at JILA, an institute jointly operated by the 麻豆免费版下载 and the National Institute of Standards and Technology (NIST), has been awarded the esteemed Nick Cobb Memorial Scholarship. Mentored by JILA Fellows and 麻豆免费版下载 professors Margaret Murnane and Henry Kapteyn, Jenkins' research focuses on pioneering tabletop extreme ultraviolet (EUV) microscopy techniques using high-harmonic generation light sources. This innovative work has positioned him as a standout recipient of this significant award.
