We visualized inhomogeneous local magnetic field (internal magnetic field) gradients arising from susceptibility contrast between an array of cylindrical glass tubes (solid matrix) and surrounding water (pore fluids) in a uniform applied magnetic fie

Complex structures often consist of many interconnected or “coupled” simpler regions. The problem frequently arises of determining the geometry of these individual subregions within the larger structure. We consider a simple model to argue that t

Nonresonant manipulation of nuclear spins can probe large volumes of sample situated in inhomogeneous fields outside a magnet, a geometry suitable for mobile sensors for the inspection of roads, buildings, and geological formations. However, the inte

Carbonate reservoirs in the Middle East are believed to contain about half of the world's oil. The processes of sedimentation and diagenesis produce in carbonate rocks microporous grains and a wide range of pore sizes, resulting in a complex spatial

We have studied the statics and dynamics of flux lines in a model for ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7\mathrm{\ensuremath{-}}\mathrm{\ensuremath{\delta}}}$, using both Monte Carlo simulations and Langevin dynamics. The lines ar

Both critical current and Shapiro steps in Josephson ladders are found to show effects of vortex exclusion below a critical magnetic field. Vortices are excluded even though the flux itself is {ital not} screened out. When current is injected perpend

We present measurements of c -axis transport in single-crystal Bi 2 Sr 2 CaCu 2 O 8 which suggest that decoupling of the superconducting CuO 2 layers occurs via a continuous crossover in this material. We discuss the process of decoupling and supplem

The phenomenology of the high Tc superconductors is discussed both at the level of the thermodynamics of melting of the Abrikosov flux lattice and in terms of the melting and kinetics of the flux lattice for a pinned system. We review results on 3D m

We have made direct measurements of the temperature dependence of the thermal diffusivity along all three axes of a single- crystal Bi 2 Ca 2 SrCu 2 O 8 superconductor. We find that the thermal diffusivity is enhanced dramatically along the Cu-O plan
