A scientist's position in the ranking is determined by their D-index (Discipline H-index), a specialized metric that exclusively considers publications and citations within the examined discipline — in this case, Physics. This focused approach provides a more precise gauge of a researcher's impact within their specific field, rather than relying on generalized measures.
Scope of Research and Ranking Criteria
The ranking assesses a total of 279,971 scientist profiles identified from diverse bibliometric data sources encompassing all scientific disciplines. Among these, 3 scientists specifically from the field of Physics were examined in detail. To qualify for inclusion in the ranking, a scientist’s D-index must be at least 70, and the majority of their tier publications are required to be within the domain of Physics.
Beyond bibliometric thresholds, consideration is also given to scientists’ awards and notable achievements within the field of Physics, further validating their status as leaders in the discipline. The D-index threshold is set in increments of 10, calibrated according to the estimated population size of scholars within each discipline. This methodology ensures that the top 1% of leading scholars in each scientific area are represented in the list. Additionally, a proximity of 30% or less between a researcher’s general H-index and their D-index is required to maintain consistency and disciplinary focus.
Additional Verification Practices
Recognizing the limitations of raw bibliometric data as an absolute measure of scholarly output, the researchers behind this ranking undertook rigorous manual verification procedures. Every scientist profile was meticulously reviewed and cross-correlated against publications listed in a wide range of trustworthy and authoritative sources. This multi-layered validation enhances the reliability and credibility of the ranking.
Though not directly influencing a researcher’s ranking position, the volume of papers published in prominent journals and conference proceedings serves as a valuable secondary indicator of a scientist’s contribution to their field. The position within the ranking ultimately derives from each researcher’s D-index, calculated based on data from OpenAlex and CrossRef.
