We present a multiscale simulation of a crack in silicon under tensile loading that is consistent with experiment; fracture is brittle with a modest lattice-trapping energy barrier to crack… (More)
Heavy-electron metals exhibit highly correlated electronic behavior at liquid helium temperatures, with conduction-electron masses some hundred times the free-electron mass. Whether "normal,"… (More)
Anderson  has argued forcefully that the unusual properties of the high temperature super-conductors for T > T c place these materials in the universality class described by Haldane’s Luttinger… (More)
SummaryWe have exploited the spatial resolution of the magnetic sensor to provide numerical estimates of the atrial contribution to magnetic fields recorded just prior to ventricular depolarization.… (More)
Abstract I show that a weak symmetry breaking field coupled to an unconventional superconducting order parameter proposed to describe UPt 3 induces a phase transition between two vortex states.
We explore the response of an unconventional superconductor to spatially inhomogeneous antiferromagnetism (SIAFM). Symmetry allows the superconducting order parameter in the E-representation models… (More)
The elementary excitation spectrum and static structure function are calculated at several pressures, using the polarization potential theory of Aldrich and Pines. The elementary excitation spectrum… (More)
