Question 1

Which countries lead Condensed Matter Physics research?

Accepted Answer

On research quality in 2022-now, the United States, China and Germany rank highest in Condensed Matter Physics. By volume, China and the United States publish the most (10k and 5.9k works in 2022-now).

Question 2

Which institutions lead Condensed Matter Physics research?

Accepted Answer

Chinese Academy of Sciences (China) ranks first in Condensed Matter Physics on research quality in 2022-now, followed by Max Planck Society and Peking University.

Question 3

Who are the leading researchers in Condensed Matter Physics?

Accepted Answer

Counting only their work in Condensed Matter Physics, R. J. Cava, Y. Tokura and Metin Sitti have the most papers in the world top 10% for their subfield and year beyond the 10% expected.

Question 4

Where is Condensed Matter Physics research done?

Accepted Answer

The largest centres of Condensed Matter Physics research in 2022-now are Beijing (China), Tokyo (Japan), Shanghai (China) and Moscow (Russia). Among places with at least 20 works in it, it is an unusually large share of all research in Sayō, Villigen and Bariloche.

Question 5

Where is the best place to study Condensed Matter Physics?

Accepted Answer

Among universities, judged by research, Stanford University, University of California, Santa Barbara and Princeton University score highest, combining standing in the field's ranking, citation excellence, specialisation, size, growth and international reach. Research strength is one signal when choosing where to study; it does not measure teaching.

Question 6

Is Condensed Matter Physics research growing?

Accepted Answer

Output in 2022-2025 was 1% higher than in 2018-2021, peaking in 2006. The fastest-growing topics are Micro and Nano Robotics, Crystallography and Radiation Phenomena and GaN-based semiconductor devices and materials.

Question 7

What are the most cited papers in Condensed Matter Physics?

Accepted Answer

The most cited paper in Condensed Matter Physics is "Efficient iterative schemes for ab initio total-energy calculations using a plane-wave basis set" (Georg Kresse, Jürgen Furthmüller, 1996), with 123,939 citations. Next come "Optimization by Simulated Annealing" (45,251) and "Particle mesh Ewald: An N ⋅log( N ) method for Ewald sums in large systems" (31,396).
