Francesco Tafuri received his Ph.D. in physics at the University of Napoli “Federico II” in 1993, carrying out part of his research activity at Stony Brook University. Since 1994 he has been at the Second University of Napoli, first as an Assistant Professor and, since 2002, as Associate Professor. In 2001, he was a visiting scientist at the IBM’s Thomas J. Watson Research Center. Most of his experimental work has focused on the study of the Josephson effect and macroscopic quantum phenomena in superconductors with a high critical temperature and vortex matter in unconventional systems and oxide nanostructures.
Defects—in the form of vortices in superconductors or “strings” in the fabric of the universe—can reveal the state of a system at the time it was cooled.
