The 2nd edition of Research.com ranking of the best universities in the discipline of
Physics was created using data consolidated from
multiple data sources including OpenAlex and CrossRef. The bibliometric data for
evaluating the citation-based metrics were gathered on 21-12-2022. Position
in the ranking is based on a sum of D-indexes (Discipline H-index) of all ranking
researcher’s affiliated with a given institution. D-index
includes exclusively papers and citation
data for an examined discipline.
The range of our Physics research
Research.com’s best universities ranking is a reliable list of leading researchers from the area of Physics, established by means of a detailed analysis of 166,880 scientists determined from multiple bibliometric data sources. For the discipline of Physics, over 51178 scientists were examined.
What is D-index approval threshold for Physics
The D-index threshold for including a researcher to be considered is placed at 70 if most of their publications are in the discipline of Physics. The inclusion factors for scholars to be considered into the ranking of top researchers are based on the D-index, proportion of the contributions made within the specific area plus the awards and achievements of the scholars. The D-index threshold for including leading scholars is set as an increment of 10 depending on the total number of researchers assessed for each discipline whilst making sure that the top 1% of leading researchers are incorporated into the list. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.
Other verification methods
Since our main aim is to ensure that only actual scholars are mentioned in Research.com ranking we realize that metrics are never supposed to be a complete tool to quantify the work of scholars. For that reason we manually verify each profile and cross-correlate it against publications in a wide range of trustworthy sources. Even though it’s not a factor defining a researcher’s position in our ranking, the number of papers published in major journals and conference proceedings should form a credible secondary indication of their contribution to research in a given area of science. Position in the ranking is determined by each scholar’s D-index with the help of information gathered from OpenAlex and CrossRef, which are the most credible and well-established bibliometric databases of this type accessible to the scientific community. A thorough explanation of our research process can be found on our methodology page.
Our goal is to inspire researchers, businessmen and politicians around the world to investigate where leading experts are heading and to offer an opportunity for the entire scientific community to get to know who the leading experts in specific areas of study, in different countries, or even within research institutions are.
