The frequency dependent polarizabilities of the francium atom are calculated from the available data of energy levels and transition rates. Magic wavelengths for the state insensitive optical dipole trapping are identified from the calculated light shifts of the $7s$ $^{2}{S}_{1/2}$, $7p$ $^{2}{P}_{1/2,3/2}$, and $8s$ $^{2}{S}_{1/2}$ levels of the $7s$ $^{2}{S}_{1/2}\ensuremath{-}7p$ $^{2}{P}_{1/2,3/2}$ and $7s$ $^{2}{S}_{1/2}\ensuremath{-}8s$ $^{2}{S}_{1/2}$ transitions, respectively…

Many-body calculations and hyperfine-interaction effect on dynamic polarizabilities at the low-lying energy levels of Y2+

The present paper determines the precise values of magic wavelengths corresponding to the clock transitions ${5}^{2}S\text{--}{4}^{2}D$ of the ${\mathrm{Y}}^{2+}$ ion at the levels of both fine and

Isotope shifts in the $7S\rightarrow 8S$ transition of francium: measurements and comparison to ab-initio theory

We observe the electric-dipole forbidden $7s\rightarrow8s$ transition in the francium isotopes $^{208-211}$Fr and $^{213}$Fr using a two-photon excitation scheme. We collect the atoms online from an

Measurement of the 671-nm tune-out wavelength of Li7 by atom interferometry

We have measured the tune-out wavelength of lithium isotope 7 Li at 671 nm. We have used our atom interferometer to measure the phase shift due to the dynamical Stark effect as a function of the

Anisotropic dependence of tune-out wavelength near Dy 741-nm transition.

The tune-out wavelength is measured as a detuning from the nearby narrow-line 741-nm transition in 162Dy, and is the wavelength at which the total Stark shift of the ground state vanishes, and it strongly depends on the relative angle between the optical field and quantization axis due to Dy's large tensor polarizability.

Spectroscopy of Trapped $^{138}$Ba$^+$ Ions for Atomic Parity Violation and Optical Clocks

The Standard Model of particle physics describes the behavior of all known elementary particles. This theory is remarkably successful in explaining the dynamics of the subatomic world (see also the

Quantum sensing of the electron electric dipole moment using ultracold entangled Fr atoms

We propose a method to measure the electron electric dipole moment (eEDM) using ultracold entangled francium (Fr) atoms trapped in an optical lattice, yielding an uncertainty below the standard

We report the first measurement of a tune-out wavelength for ground-state bosonic Dy and linearly polarized light. The tune-out wavelength is measured as a detuning from the nearby narrow-line 741-nm
