The 2nd edition of Research.com ranking of the best scholars in the
discipline of Physics is based on data
combined 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
researcher’s D-index (Discipline H-index), which
includes exclusively papers and citation
values for an examined discipline.
The scope of our Physics research
Research.com’s best scientists ranking is a trustworthy list of leading researchers from the area of Physics, created using a detailed study of 166,880 scholars discovered from various bibliometric data sources. For the area of Physics, more than 51178 scientists were analysed.
What is D-index acceptance threshold for Physics
The D-index threshold for including a scientist to be examined is established at 70 if the majority of of their publications are in the area of Physics. The inclusion criteria for scientists to be considered into the ranking of top scholars are based on the D-index, ratio of the contributions made within the selected area plus the awards and achievements of the scholars. The D-index threshold for considering top researchers is set as an increment of 10 depending on the overall number of scholars projected for each area od study whilst making sure that the top 1% of best scientists are added into the ranking. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.
Additional verification practices
Because our main aim is to guarantee that only actual scholars are listed in our ranking we are aware that raw data are never meant to be a complete tool to assess the output of scientists. Because of that we manually verify every profile and cross-correlate it against publications in a wide range of credible sources. While it’s not a factor impacting a scientist’s position in Research.com ranking, the amount of documents published in major journals and conference proceedings should form a reliable secondary indication of their contribution to research in a selected area of science. Position in the ranking is determined by every researcher’s D-index according to data collected from OpenAlex and CrossRef, which are the most prominent and well-known bibliometric databases of this kind accessible to the research community. A detailed definition of our research policy can be found on our methodology page.
Our aim is to motivate researchers, businessmen and administrative bodies worldwide to explore where prominent experts are heading and to give an opportunity for the whole research community to discover who the leading experts in specific areas of study, in different countries, or even within research institutions are.
