Zlatko Tesanovic is a Professor of Physics at The Johns Hopkins University in Baltimore, MD. His research interests are in theoretical condensed matter physics, revolving primarily around high temperature superconductors and related materials, quantum Hall effects, and other manifestations of strong correlations and emergent behavior in quantum many-particle systems.
Are electronic correlations in the new iron-pnictide high-temperature superconductors as strong as in their older cuprate brethren? Yes, say some physicists; no, say others. X-ray experiments deliver the verdict.
