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…
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…
Controlling Th isomeric state population in a VUV transparent crystal
Takahiro Hiraki, Koichi Okai, Michael Bartokos +27
The radioisotope Th-229 is renowned for its extraordinarily low-energy, long-lived nuclear first-excited state. This isomeric state can be excited by VUV lasers and the transition…
