Nuclear-size correction to the one-loop self-energy in hydrogenlike ions
Ping Yang, Aleksei V. Malyshev, Aleksandr N. Kochnev +4
The nuclear-size effect on both diagonal and off-diagonal one-loop self-energy matrix elements is considered for hydrogenlike ions with , , , and . Specifically,…
QED corrections of orders and for HD rovibrational transitions beyond Born-Oppenheimer approximation
Zhen-Xiang Zhong, Ping Yang, Vladimir I. Korobov +2
The effective Hamiltonian of and order corrections for hydrogen molecular ions has been derived in [ Z.-X. Zhong, \emph{et al.}, Phys. Rev. A {\bf98}, 032502(201…
Precise ab initio calculations of He() fine structure of high Rydberg states
Hao Fang, Jing Chi, Xiao-Qiu Qi +3
High-precision measurements of the fine-structure splittings in helium high Rydberg states have been reported, yet corresponding ab initio benchmarks for direct comparison remain u…
Direct Extraction of Nuclear Structure Information Using Precision Lithium-Ion Spectroscopy
Hua Guan, Xiao-Qiu Qi, Jian-Guo Li +14
Accurately describing nuclear interactions within atomic nuclei remains a challenge, which hinders our exploration of new physics beyond the Standard Model. However, these nuclear…
