How to search for institutions/universities that have good contributions on a certain physics research topic?
Statistics on institutions should be taken with 14,000,000 grains of salt: some institutions have changed name over time (including many recently, e.g. in France many institutions were forking twenty years ago and are now merging back), and affiliation rules vary widely between authors (you'll see below huge contributions from state-wide agencies like “Russian academy of science” or “CNRS”, they are not the same as universities or labs). But, you can do it with many bibliographic search tools.

Here's how to do with Web of Science:


Make a regular search (here I chose “title”, but you can do something more complicated)

On the results page, click on the “Analyze Results” link

Choose your field of interest (here, organizations)

Enjoy!
