He holds an MA degree from the Architectural Association in London. His dissertation concerns architectural and art historical debates surrounding the Neo-baroque at the end of the nineteenth century in Germany

    Magnetic field independence of the spin gap in YBa_2Cu_3O_{7-delta}

    We report, for magnetic fields of 0, 8.8, and 14.8 Tesla, measurements of the temperature dependent ^{63}Cu NMR spin lattice relaxation rate for near optimally doped YBa_2Cu_3O_{7-delta}, near and above T_c. In sharp contrast with previous work we find no magnetic field dependence. We discuss experimental issues arising in measurements of this required precision, and implications of the experiment regarding issues including the spin or pseudo gap.Comment: 4 pages, 3 figures, as accepted for publication in Physical Review Letter
