Ionization potential and electron affinity of superheavy element 119: relativistic high-order coupled cluster study with QED corrections
A. R. Saetgaraev, L. V. Skripnikov, I. I. Tupitsyn +5
We report a highly accurate \textit{ab initio} study of the ionization potential (IP) and electron affinity (EA) of element 119. Electronic correlation are treated within the relat…

On the rank-reduced relativistic coupled cluster method
Alexander V. Oleynichenko, Artem S. Rumiantsev, Andrei Zaitsevskii +1
An efficiency of the Tucker decomposition of amplitude tensors within the single-reference relativistic coupled cluster method with single and double excitations (RCCSD) was studie…
