David D. Awschalom, Michael E. Flatté and Nitin Samarth began working as a team when Flatté was recently on sabbatical at the University of California, Santa Barbara. Awschalom and Samarth had already been collaborating on experimental studies of semiconductor spintronics for more than a decade. Awschalom is professor of physics and director of the Center for Spintronics and Quantum Computation at U.C.S.B. Flatté works on condensed-matter theory and is associate professor at the University of Iowa. Samarth is professor of physics at Pennsylvania State University.
