The 2nd edition of Research.com ranking of the best scientists in the
field of Physics is based on data
combined from various data sources including OpenAlex and
CrossRef. The bibliometric data for devising the citation-based metrics were
gathered on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
includes exclusively papers and citation
values for an examined discipline.
The range of our Physics research
Research.com’s best scientists ranking is a credible list of leading scholars from the field of Physics, established by means of a detailed analysis of 166,880 researchers discovered from various bibliometric data sources. For the discipline of Physics, as many as 51178 researchers were examined.
What is D-index acceptance threshold for Physics
The D-index threshold for including a scientist to be examined is established at 70 if most of their publications are in the area of Physics. The approval requirements for scientists to be considered into the ranking of top scholars are based on the D-index, ratio of the publications made within the selected discipline in addition to the awards and achievements of the scientists. The D-index threshold for listing best scholars is set as an increment of 10 depending on the overall number of researchers projected for each discipline whilst making sure that the top 1% of best researchers are added into the ranking. There should be a proximity of 30% or less between a scholar’s general H-index and their D-index.
Additional verification rules
Because our leading aim is to ensure that only actual scientists are mentioned in the ranking we are aware that raw data are never meant to be an absolute tool to evaluate the work of scientists. This is why we manually inspect each profile and cross-correlate it against publications in a wide range of credible sources. Although it’s not a metric contributing to a researcher’s position in our ranking, the number of documents published in well-known journals and conference proceedings should constitute a credible secondary signal of their contribution to research in a specific field of study. Position in the ranking is based on each scientist’s D-index according to metrics gathered from OpenAlex and CrossRef, which are the most credible and well-known bibliometric databases of this kind accessible to the research community. A comprehensive overview of our research policy can be found on our methodology page.
Our aim is to inspire scientists, companies and politicians around the world to examine where top experts are heading and to provide an opportunity for the entire scientific community to discover who the leading experts in specific areas of study, in different countries, or even within research institutions are.
