Relativistic Complete Active Space Self-consistent-Field Method with a Hierarchy of Exact Two-Component Hamiltonians
Xubo Wang, Sen Wang, Yixuan Wu +1
The development of a novel exact two-component (X2C) scheme with the inclusion of the picture-change correction for the fluctuation potential, the X2Ccorr scheme, is reported, here…

Hyperfine-Resolved Spectroscopy of Dysprosium Monoxide (DyO) for Precision Measurements of the Nuclear Schiff Moment
Zack D. Lasner, Aidan T. Ohl, Nicole M. Albright +5
We perform laser spectroscopy of dysprosium monoxide (DyO) to determine the hyperfine structure of the ground X8 and excited [17.1]7 states in the Dy and Dy isotopo…

Relativistic Two-Electron Contributions within Exact Two-Component Theory
Xubo Wang, Chaoqun Zhang, Junzi Liu +1
The development of relativistic exact two-component (X2C) theory is briefly reviewed, with an emphasis on cost-effective treatments of relativistic two-electron contributions by me…
