For example, I am interested in the research related with "Quantum Hall Effects", and want to have a list of institutions/universities that have good contributions in this topic, with number of publications during the recent years. Any idea how? Is there any website provide such searching service? Google scholar, arXiv?
I tried APS search by searching "Quantum Hall Effects" in Abstract/Title. It shows all related papers. But now I just want to know the statistics of the institutional contributions.
Any idea how?
