Analytical and numerical studies of periodic superradiance
Hideaki Hara, Yuki Miyamoto, Junseok Han +6
We conduct a theoretical study to understand the periodic superradiance observed in an Er:YSO crystal. First, we construct a model based on the Maxwell-Bloch equations for a reduce…
Control of emission interval and timing in triggered periodic superradiance
Hideaki Hara, Riku Omoto, Noboru Sasao +6
To achieve more controllable development of coherence in solids, we investigated the effect of a trigger laser tuned to the superradiance transition wavelength on periodic superrad…
A method to detect the VUV photons from cooled Th:CaF crystals
Ming Guan, Michael Bartokos, Kjeld Beeks +13
Thorium-229, with its exceptionally low-energy nuclear excited state, is a key candidate for developing nuclear clocks. Th-doped CaF crystals, benefiting from calcium f…
Measurement of cesium electric quadrupole transition probabilities using fluorescence spectroscopy
Jing Wang, Yuki Miyamoto, Hideaki Hara +3
Fluorescence spectra of the ( and = 3/2, 1/2) electric quadrupole transition of cesium atoms have been observed with a heated cesium vapor cell…
