The 2nd edition of Research.com ranking of the best scholars in the
field of Physics relies os data
consolidated from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
acquired on 21-12-2022. Position in the ranking is based on a
scholar’s D-index (Discipline H-index), which
only includes papers and citation
metrics for an examined discipline.

The focus of our Physics research
Our best researchers ranking is a reliable
account of leading researchers from the area of
Physics, based on a meticulous
study of 166,880 scientists identified
from various bibliometric data sources. For the discipline of
Physics, more than 51178 scholars were
examined.
What is D-index approval threshold for Physics
The D-index threshold for accepting a scientist to be
considered is set to 70 if
most of their publications are in the area of Physics. The
acceptance criteria for researchers to be
considered into the ranking of top scholars are based on the D-index, proportion
of the publications made within the selected area
in addition to the awards and achievements of the scholars. The
D-index threshold for listing top researchers is
set as an increment of 10 depending on the overall number of scholars
projected for each area od study whilst
ensuring that the top 1% of best scientists are
incorporated into the ranking. We estimate a proximity of
30% or less between a researcher’s general H-index and their D-index.
Extra verification rules
Since our leading mission is to ensure that only
genuine researchers are included in
Research.com ranking we are aware that raw data are never
meant to be a full measure to assess the
output of scientists. Because of that
we manually check each profile and cross-correlate it against publications in a
wide range of trustworthy sources. Although it’s not a
metric contributing to a scientist’s position in
Research.com ranking, the quantity of documents published in
major journals and conference proceedings should be a
credible secondary implication of their contribution to research in a
specific discipline. Position in the ranking is
determined by each scholar’s D-index
with the help of metrics compiled from OpenAlex and
CrossRef, which are the most trustworthy and well-known bibliometric
databases of this kind available to the research community. A
thorough explanation of our research policy
can be found on our
methodology page.
Our goal
Our goal is to inspire scientists,
businessmen and decision-makers
around the world to investigate where prominent experts are heading
and to provide a way for the entire scientific community to
find out who the leading experts in specific
disciplines, in different countries, or even within research
institutions are.
