Accepted Answer

The most-cited researchers publishing on Atomic and Molecular Physics include M. Shoji, John P. Perdew and Georg Kresse.

Question 4

Where is Atomic and Molecular Physics research done?

Accepted Answer

The largest centres of Atomic and Molecular Physics research in 2022-now are Beijing (China), Moscow (Russia), Paris (France) and Saint Petersburg (Russia). Among places with at least 20 works in it, it is an unusually large share of all research in Dubna, Livermore and Darmstadt.

Question 5

Where is the best place to study Atomic and Molecular Physics?

Accepted Answer

Among universities, judged by research, Peking University, University of Chinese Academy of Sciences and KU Leuven score highest, combining excellence, specialisation, size, growth and international reach. Research strength is one signal when choosing where to study; it does not measure teaching.

Question 6

Accepted Answer

Output in 2022-2025 was 19% lower than in 2018-2021, peaking in 2013.

Question 7

What are the most cited papers in Atomic and Molecular Physics?

Accepted Answer

The most cited paper in Atomic and Molecular Physics is "Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density" (Chengteh Lee, Weitao Yang, Robert G. Parr, 1988), with 101,337 citations. Next come "Projector augmented-wave method" (93,392) and "The calculation of small molecular interactions by the differences of separate total energies. Some procedures with reduced errors" (22,220).
