类碱金属离子极化率、魔幻波长和幻零波长的理论研究进展
Theoretical study advances on the polarizability,magic wavelength,and tune-out wavelength of alkali-like ions
摘要
Abstract
Polarizability is a physical quantity that describes the degree to which the electron cloud of an atom deviates from its normal distribution in an external electric field.It plays a crucial role in the development of atomic optical clocks,precise measurements of radiation spectra,and the computation of ultracold atoms and quantum information.Our research group has developed a relativistic configuration interaction potential(RCICP)method and program centered around ion systems related to atomic clocks.We systematically calculated basic structural parameters such as wave functions,energy levels,and matrix elements for alkali-like ions Ca+,Ba+,and Yb+.Using these structural parameters,we further calculated the polarizability of clock transition states.Subsequently,we conducted a detailed study on the magic wavelength and tune-out wavelength of these ion clock transitions,and analyzed the relationship between the magic wavelength and the variation of laser polarization angle,providing theoretical data support for corresponding experimental measurements.关键词
