Exploring $\hat{I}\pm$- and ${\hat{I}}^2$-decay-induced quenching of the ${}^{229}$Th nuclear-clock isomer in solid-state hosts

The radiative decay dynamics of an ensemble of ${}^{229\mathrm{m}}$Th nuclei embedded in CaF${}_2$ and MgF${}_2$ is investigated. The isomer is populated through ${\hat{I}}^2$ decay of ${}^{229}$Ac…
