Atomic Properties

An expansion method is used to calculate the expectation values of various operators for the lowest 2 S and 2 P 0 states of all members of the lithium sequence. The method is extended to the calculation of matrix elements connecting the two states and the electric dipole transition integrals are calculated. A comparison with the results of more refined calculations shows that despite its simplicity the method is capable of high accuracy.

Dipole Polarizabilities

Active clocks could provide better stabilities during initial stages of measurements over passive clocks, in which stabilities become saturated only after long-term measurements. This unique feature of an active clock has led to search for suitable candidates to construct such clocks. The other challenging task of an atomic clock is to reduce its possible systematics. A major part of the optical lattice atomic clocks based on neutral atoms are reduced by trapping atoms at the magic wavelengths of the optical lattice lasers. Keeping this in mind, we find the magic wavelengths between all possible hyperfine levels of the transitions in Rb and Cs atoms that were earlier considered to be suitable for making optical active clocks. To validate the results, we give the static dipole polarizabilities of Rb and Cs atoms using the electric dipole transition amplitudes that are used to evaluate the dynamic dipole polarizabilities and compare them with the available literature values.

Best Fit

Stevenson's principle of minimal sensitivity is used in renormalizing radiative corrections to hyperfine splittings, leptonic and hadronic decay widths, and electric-dipole transition rates. Numerical values for these quantities are presented for the charmonium and bottomonium systems, enlisting several nonrelativistic phenomenological potential models to determine the best fit to the experimental data. It is shown that good results may be obtained within a single model in which the value of ΛQCD is calculated and kept constant for all predictions within that model.
