John M. Tranquada
John Tranquada is leader of the neutron scattering group at Brookhaven National Lab and a principal investigator in the Center for Emergent Superconductivity, an Energy Frontier Research Center. He received his B.A. and Ph.D. in physics from Pomona College and the University of Washington, respectively. He continues to enjoy studying high-temperature superconductors, primarily with neutron scattering techniques.
Measurements with a scanning probe microscope sensitive to micron-scale magnetization variations provide evidence for stripes of enhanced superfluid density at the surface of an iron-pnictide superconductor.
