I propose the index ℏ (“hbar”), defined as the number of papers of an individual that have citation count larger than or equal to the ℏ of all coauthors of each paper, as a useful index to characterize the scientific output of a researcher that takes into account the effect of multiple authorship. The bar is higher for ℏ.
