The time of arrival problem in the Page-Wootters formalism
Niyusha Hosseini, Maximilian P. E. Lock
The time-of-arrival problem asks for the probability distribution for when a quantum particle reaches a specified location. It has been the subject of decades of debate, exemplifyi…
Optical Transmission Enhancement of Ionic Crystals via Superionic Fluoride Transfer: Growing VUV-Transparent Radioactive Crystals
Kjeld Beeks, Tomas Sikorsky, Fabian Schaden +11
The 8 eV first nuclear excited state in Th is a candidate for implementing an nuclear clock. Doping Th into ionic crystals such as CaF is expected to suppress n…
Growth and characterization of thorium-doped calcium fluoride single crystals
Kjeld Beeks, Tomas Sikorsky, Veronika Rosecker +13
We have grown Th:CaF and Th:CaF single crystals for investigations on the VUV laser-accessible first nuclear excited state of Th. To reach high dopi…
Observation of the radiative decay of the nuclear clock isomer
Sandro Kraemer, Janni Moens, Michail Athanasakis-Kaklamanakis +32
The nucleus of the radioisotope thorium-229 (Th) features an isomer with an exceptionally low excitation energy that enables direct laser manipulation of nuclear states.…
