“…It was proposed that the 229 Th isomeric decay could be identified via electromagnetically modified nuclear forward scattering. An optomechanical microlever was proposed to bridge the gap between an optical laser and X-rays in [207]. It was emphasized that such a device could have significant implications for 229m Th and, in particular, could be applied for the isomer's energy determination.…”

The proposal for the development of a nuclear optical clock has triggered a multitude of experimental and theoretical studies. In particular the prediction of an unprecedented systematic frequency uncertainty of about $$10^{-19}$$ 10 - 19 has rendered a nuclear clock an interesting tool for many applications, potentially even for a re-definition of the second. The focus of the corresponding research is a nuclear transition of the $$^{229}$$ 229 Th nucleus, which possesses a uniquely low nuclear excitation energy of only $$8.12\pm 0.11$$ 8.12 ± 0.11 eV ($$152.7\pm 2.1$$ 152.7 ± 2.1 nm). This energy is sufficiently low to allow for nuclear laser spectroscopy, an inherent requirement for a nuclear clock. Recently, some significant progress toward the development of a nuclear frequency standard has been made and by today there is no doubt that a nuclear clock will become reality, most likely not even in the too far future. Here we present a comprehensive review of the current status of nuclear clock development with the objective of providing a rather complete list of literature related to the topic, which could serve as a reference for future investigations.

We investigate the multiphoton quantum dynamics of a leaking single-mode quantized cavity field coupled with a resonantly driven two-level qubit possessing permanent dipoles. The frequencies of the interacting subsystems, i.e. cavity and the emitter, are being considered very different, e.g. microwave and optical domains, respectively, and therefore the latter one couples to the resonator mode via its parallel dipole moments. As well, the generalized Rabi frequency resulting form the external coherent driving of the two-level qubit is assumed different from the resonator's frequency. As a consequence, this highly dispersive interaction regime is responsible for the cavity multiphoton quantum dynamics and photon conversion from optical to microwave ranges, respectively.

“…We go beyond the previous results in Refs. [16,21,22] to show that each excitation scheme requires analysis of the crystal structure and dopant orien-arXiv:1809.01857v4 [physics.atom-ph] 17 Jan 2019 tation, which give information not only on the hyperfine structure of the levels to be driven, but also on the orientation of the possible quantization axes. The hyperfine structure determines the required energies to drive transitions as well as the angular momentum selection rules in the frame of each individual Th nucleus.…”

Vacuum-ultraviolet-transparent crystals have been proposed as host lattice for the coherent driving of the unusually low-lying isomer excitation in 229 Th for metrology and quantum optics applications. Here the possible collective effects occurring for the coherent pulse propagation in the crystal system are investigated theoretically. We consider the effect of possible doping sites, quantization axis orientation and pulse configurations on the scattered light intensity and signatures of nuclear excitation. Our results show that for narrow-pulse driving, the rather complicated quadrupole splitting of the level scheme is significantly simplified. Furthermore, we investigate complex driving schemes with a combination of pulsed fields and investigate the occurring interference process. Our theoretical results support experimental attempts for first direct driving of the nuclear transition with coherent light.
