An alternative method to determine the excitation energy of the ^229m Th isomer via the laser-induced electronic bridge is investigated theoretically. In the presence of an optical or ultra-violet laser at energies that fulfill a two-photon resonance

The electronic defect states resulting from doping $^{229}\mathrm{Th}$ in ${\mathrm{CaF}}_{2}$ offer a unique opportunity to excite the nuclear isomeric state $^{229\mathrm{m}}\mathrm{Th}$ at approximately 8 eV via electronic bridge mechanisms. We co

When Th nuclei are doped in ${\mathrm{CaF}}_{2}$ crystals, a set of electronic defect states appear in the crystal band gap which would otherwise provide complete transparency to vacuum-ultraviolet radiation. The coupling of these defect states to th

A comprehensive theoretical study of direct laser excitation of a nuclear state based on the density matrix formalism is presented. The nuclear clock isomer $$^{229\text {m}}$$ Th is discussed in detail, as it could allow for direct laser excitation

The first nuclear excited state of $^{229}$Th offers the unique opportunity for laser-based optical control of a nucleus. Its exceptional properties allow for the development of a nuclear optical clock which offers a complementary technology and is e

The unique isomeric transition at 7.8 eV in $^{229}\mathrm{Th}$ has a magnetic-dipole ($M1$) and an electric-quadrupole ($E2$) multipole mixing. So far, the $E2$ component has been widely disregarded. Here, we investigate the nuclear physics nature a
