Fe-based superconductors: unity or diversity?

Abstract

Does the high temperature superconductivity observed in the newly discovered iron-pnictide materials represent another example of the same essential physics responsible for superconductivity in the cuprates, or does it embody a new mechanism?

Some minor errors in the figure and in the reference in the published version are corrected. 2 pages, 2 figures
