The heavy Fermion material $PrOs_4Sb_{12}$ (POS) exhibits two superconducting transitions. Recently, the superconducting state at lower temperature has been reported to break time-reversal symmetry. This is an exciting development because of the possibility that such a state could provide a 3d platform for Majorana fermions. I will describe how inelastic light scattering can be used to determine the full pairing symmetry in POS.
Professor Philip Phillips received his bachelor's degree from Walla Walla College in 1979, and his Ph.D. from the University of Washington in 1982. After a Miller Fellowship at Berkeley, he joined the faculty at Massachusetts Institute of Technology (1984-1993). Professor Phillips came to the University of Illinois in 1993.
Professor Phillips is a theoretical condensed matter physicist who has an international reputation for his work on transport in disordered and strongly correlated low-dimensional systems. He is the inventor of various models for Bose metals, Mottness, and the random dimer model, which exhibits extended states in one dimension, thereby representing an exception to the localization theorem of Anderson's.
