Systematic evaluation of an atomic clock at 2 × 10−18 total uncertainty
TLDR
This work performs a new accuracy evaluation of the JILA Sr clock, reducing many systematic uncertainties that limited previous measurements, such as those in the lattice ac Stark shift, the atoms' thermal environment and the atomic response to room-temperature blackbody radiation. Expand
TOPICAL REVIEW: Theory and applications of atomic and ionic polarizabilities
Atomic polarization phenomena impinge upon a number of areas and processes in physics. The dielectric constant and refractive index of any gas are examples of macroscopic properties that are largelyExpand
Search for New Physics with Atoms and Molecules
Advances in atomic physics, such as cooling and trapping of atoms and molecules and developments in frequency metrology, have added orders of magnitude to the precision of atom-based clocks andExpand
Blackbody-radiation shift in the Sr optical atomic clock
We evaluated the static and dynamic polarizabilities of the $5{s}^{2}\phantom{\rule{0.16em}{0ex}}{}^{1}{S}_{0}$ and $5s5p\phantom{\rule{0.16em}{0ex}}{}^{3}{P}_{0}^{o}$ states of Sr using theExpand
Frequency-dependent polarizabilities of alkali-metal atoms from ultraviolet through infrared spectral regions
We present results of first-principles calculations of the frequency-dependent polarizabilities of all alkali-metal atoms for light in the wavelength range 300-1600 nm, with particular attention toExpand
Spectroscopic observation of SU(N)-symmetric interactions in Sr orbital magnetism
TLDR
This study lays the groundwork for using alkaline-earth atoms as testbeds for important orbital models by probing the non-equilibrium two-orbital SU(N) magnetism via Ramsey spectroscopy of atoms confined in an array of two-dimensional optical traps. Expand
Tune-out wavelengths of alkali-metal atoms and their applications
Using first-principles calculations, we identify ''tune-out'' optical wavelengths, {lambda}{sub zero}, for which the ground-state frequency-dependent polarizabilities of alkali-metal atoms vanish.Expand
Alkaline-Earth Atoms in Optical Tweezers
We demonstrate single-shot imaging and narrow-line cooling of individual alkaline earth atoms in optical tweezers; specifically, strontium-88 atoms trapped in $515.2~\text{nm}$ light. We achieveExpand
Nuclear magnetic moment of 210Fr: a combined theoretical and experimental approach.
TLDR
The theoretical value, obtained using the relativistic all-order method from the electronic wave function at the nucleus, allows us to extract a nuclear magnetic moment of 4.38(5)micro_{N} for this isotope, which represents a factor of 2 improvement in precision over previous measurements. Expand
HIGH-PRECISION CALCULATIONS OF DISPERSION COEFFICIENTS, STATIC DIPOLE POLARIZABILITIES, AND ATOM-WALL INTERACTION CONSTANTS FOR ALKALI-METAL ATOMS
The van der Waals coefficients for the alkali-metal atoms from Na to Fr interacting in their ground states are calculated using relativistic ab initio methods. The accuracy of the calculations isExpand
