Physicists at 蜜桃传媒破解版下载 have demonstrated a new kind of vacuum ultraviolet laser that could one day allow scientists to observe phenomena currently out of reach for the most powerful microscopes.
The new laser could allow researchers to follow fuel molecules in real time as they undergo combustion, spot incredibly small defects in nanoelectronics, track time with unprecedented precision and more.
The JILA team will present its preliminary findings on March 17 and March 19 at the American Physical Society Global Physics Summit in Denver.
A team led by JILA Fellows and 蜜桃传媒破解版下载 professors Margaret Murnane and Henry Kapteyn has made a significant advance to make soft X-rays more accessible: with their research group, they have developed an ultrastable, scalable and repeatable method for generating soft X-ray beams using a custom-built 3-micron ultrafast laser that is focused into an anti-resonant hollow-core fiber.
Congratulations to JILA graduate students Anya Grafov and Iona Binnie鈥攚ho conduct their cutting-edge research in the laboratory of JILA Fellows and the University of Colorado Boulder professors Margaret Murnane and Henry Kapteyn鈥攆or their outstanding achievements at the MMM Intermag 2025 conference!
Researchers at JILA have developed a novel microscope that makes examining ultrawide-bandgap semiconductors possible on an unprecedented scale. The team鈥檚 work, recently published in Physical Review Applied, introduces a tabletop deep-ultraviolet (DUV) laser that can excite and probe nanoscale transport behaviors in materials such as diamond. This microscope uses high-energy DUV laser light to create a nanoscale interference pattern on a material鈥檚 surface, heating it in a controlled, periodic pattern. Observing how this pattern fades over time provides insights into the electronic, thermal, and mechanical properties at spatial resolutions as fine as 287 nanometers, well below the wavelength of visible light.
JILA graduate student Clay Klein has been awarded the prestigious 2025 Nick Cobb Memorial Scholarship, presented by SPIE, the International Society for Optics and Photonics, and Siemens EDA. The scholarship, valued at $10,000, recognizes Klein鈥檚 outstanding contributions to the field of optics and photonics.
JILA and University of Colorado Boulder Physics graduate student Emma Nelson achieved notable recognition by securing 3rd place at the 蜜桃传媒破解版下载 2024 Innovation in Materials Symposium on August 15, 2024. Held at 蜜桃传媒破解版下载, this symposium is a significant platform for the materials research community, bringing together faculty, students, and industry professionals from 蜜桃传媒破解版下载 and beyond. The event is dedicated to supporting interdisciplinary collaboration and furthering discussions in the field of materials science.
Anya Grafov, a graduate student at JILA, has been awarded the Best Poster Award at the IEEE Magnetics Society Summer School 2024. Studying under JILA Fellows and University of Colorado Boulder Physics professors Margaret Murnane and Henry Kapteyn, Grafov's poster titled 鈥淧robing Ultrafast Spin Dynamics with Extreme Ultraviolet High Harmonics鈥 was one of only nine to receive this prestigious recognition.
Yunzhe 鈥淥liver鈥 Shao, a graduate student at JILA in the group led by JILA Fellows and University of Colorado Boulder Physics professors Margaret Murnane and Henry Kapteyn, has been awarded the Best Paper Award at the IEEE Conference on Computational Imaging Using Synthetic Apertures.
Nick Jenkins, a graduate student at JILA, an institute jointly operated by the University of Colorado Boulder and the National Institute of Standards and Technology (NIST), has been awarded the esteemed Nick Cobb Memorial Scholarship. Mentored by JILA Fellows and University of Colorado Boulder 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.
As reported in a new Science Advances paper, the JILA team and collaborators from universities in Sweden, Greece, and Germany probed the spin dynamics within a special material known as a Heusler compound: a mixture of metals that behaves like a single magnetic material. For this study, the researchers utilized a compound of cobalt, manganese, and gallium, which behaved as a conductor for electrons whose spins were aligned upwards and as an insulator for electrons whose spins were aligned downwards.
