| Abstract | The primary motivation of this work is the development of atomic clocks and the searches for new physics beyond the standard model. Optical clocks based on the forbidden transitions in an atom have been shown to be promising candidates for a better frequency standard. The search for new physics beyond the standard model can be done by looking for tiny deviations of atomic properties which is not expected by this model. Highly precise calculations for atomic systems are needed to provide further understanding in these studies. ☐ The main formalisms that we use for the calculation on the atomic systems are all-order method, which is based on linear single double coupled cluster (LCCSD) method, and the combination of configuration interaction (CI) and all-order meth- ods. These methods are suitable to study open-shell atomic systems and capable of calculating the electron correlations up to all order. ☐ In this work, we carried out the following calculations. First, we proposed a new method of determining transition matrix elements using the measurement of magic wavelength in Sr lattice clock. Next, we calculated the blackbody radiation shift in Tl + and Hg, the magic wavelength in Hg, and the hyperfine quenching rate in Cd. Next, we developed a method to calculate the specific mass shift in the all-order formalism and apply it to Na, K, and Rb atoms. Next, we calculated Ra atomic properties for electric dipole moment (EDM) experiments, and parity non-conserving amplitude of Cs and Fr. Finally, we calculated the energies and transition matrix elements of highly charged Mo and Tc ions. | en_US |
