“…These results are directly applicable to trapped Th m+ ions with m ≥ 4 and, with a minor modification, to Th in a large-bandgap crystal. The modification in the latter case is due to the polarization of the dielectric medium and leads to a reduction of the half-life by a factor of 1/n 3 [25,50], where n denotes the refractive index. The calculated half-lifes can further be used in the trapped ion approach with m < 4 to calculate e.g.…”

We estimate the range of the radiative lifetime and energy of the anomalous, low-energy 3/2 + (7.8± 0.5 eV) state in the 229 Th nucleus. Our phenomenological calculations are based on the available experimental data for the intensities of M 1 and E2 transitions between excited levels of the 229 Th nucleus in the K π [N nZ Λ] = 5/2 + [633] and 3/2 + [631] rotational bands. We also discuss the influence of certain branching coefficients, which affect the currently accepted measured energy of the isomeric state. From this work, we establish a favored region where the transition lifetime and energy should lie at roughly the 90% confidence level. We also suggest new nuclear physics measurements, which would significantly reduce the ambiguity in the present data.

Exciton-plasmon coupling interactions: from principle to applications

Abstract:The interaction of exciton-plasmon coupling and the conversion of exciton-plasmon-photon have been widely investigated experimentally and theoretically. In this review, we introduce the exciton-plasmon interaction from basic principle to applications. There are two kinds of exciton-plasmon coupling, which demonstrate different optical properties. The strong exciton-plasmon coupling results in two new mixed states of light and matter separated energetically by a Rabi splitting that exhibits a characteristic anticrossing behavior of the exciton-LSP energy tuning. Compared to strong coupling, such as surface-enhanced Raman scattering, surface plasmon (SP)-enhanced absorption, enhanced fluorescence, or fluorescence quenching, there is no perturbation between wave functions; the interaction here is called the weak coupling. SP resonance (SPR) arises from the collective oscillation induced by the electromagnetic field of light and can be used for investigating the interaction between light and matter beyond the diffraction limit. The study on the interaction between SPR and exaction has drawn wide attention since its discovery not only due to its contribution in deepening and broadening the understanding of SPR but also its contribution to its application in light-emitting diodes, solar cells, low threshold laser, biomedical detection, quantum information processing, and so on.

“…The majority of researchers in this field [11][12][13][14][15], in fact, endorse the Lorentz factor. On the other hand, experimental results [16] on atoms inside complexes indicate that the emptycavity factor should be employed. These factors differ very much, especially for frequencies near a band gap or a material resonance where´can become very large.…”

“…It has been proposed theoretically [10][11][12][13][14][15][16][17] that one of the factors, L Lor or L emp , should be included in a description of G of impurity atoms inside dielectrics. The majority of researchers in this field [11][12][13][14][15], in fact, endorse the Lorentz factor.…”
