Record nonlinear conversion efficiency in the production of high spectral purity vacuum ultraviolet laser at 148 nm
Sergey Vasilyev, Tian Ooi, Igor Moskalev +14
Coherent vacuum-ultraviolet (VUV) lasers are indispensable for precision measurement, quantum optics, and materials science. Recent high-resolution spectroscopy of the Th-229 nucle…
Probing Ultralight Dark Matter at the Mega-Planck Scale with the Thorium Nuclear Clock
Jason Arakawa, Jack F. Doyle, Elina Fuchs +10
Ultralight dark matter is expected to induce oscillations of nuclear parameters. These oscillations are characterized by extremely weak couplings or high suppression scales, with t…
Frequency reproducibility of solid-state Th-229 nuclear clocks
Tian Ooi, Jack F. Doyle, Chuankun Zhang +5
Solid-state Th nuclear clocks are set to provide new opportunities for precision metrology and fundamental physics. Taking advantage of a nuclear transition's inherent low…
Temperature sensitivity of a Thorium-229 solid-state nuclear clock
Jacob S. Higgins, Tian Ooi, Jack F. Doyle +5
Quantum state-resolved spectroscopy of the low energy thorium-229 nuclear transition was recently achieved. The five allowed transitions within the electric quadrupole structure we…
