Defect Dynamics and Isomer Quenching in Th:CaF Crystals
Ming Guan, Michael Bartokos, Kjeld Beeks +16
Thorium-229 doped calcium fluoride (Th:CaF) is a leading candidate for a solid-state nuclear clock, owing to the unusually low energy of the Th isomer transitio…
Analytical study of birefringent cavities for axion-like dark matter search
Tadashi Kuramoto, Yasutaka Imai, Takahiko Masuda +3
Light polarization plays a crucial role in optical-cavity experiments; however, mirror birefringence presents a significant challenge that must be addressed carefully. In this stud…
Constraints on the polarization angle oscillations of the Crab Nebula with the Simons Array and its applications to the search for axion-like particles
Tylor Adkins, Shahed Shayan Arani, Kam Arnold +27
We present a search for polarization oscillation of the Crab Nebula, also known as Tau A, at millimeter wavelengths using observations with the Simons Array, the successor experime…
Laser Mössbauer spectroscopy of ^{229}Th
Takahiro Hiraki, Takahiko Masuda, Sayuri Takatori +23
Mössbauer spectroscopy is widely used in biochemistry, geology, and solid-state physics to obtain structural information on materials. Here, we extend this technique into the optic…
X-ray-induced quenching of the Th clock isomer in CaF
Ming Guan, Michael Bartokos, Kjeld Beeks +27
Thorium-229 has the lowest nuclear-excited state (an isomer state) at approximately 8.356 eV, making it excitable with tabletop vacuum-ultraviolet lasers. Despite the recent succes…
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…
