We report measurements of the spin susceptibility in dilute two-dimensional electrons confined to a 45 A wide AlAs quantum well. The electrons in this well occupy an out-of-plane conduction-bandâ€¦ (More)

We report phenomena manifesting nonequilibrium superconductivity induced by spin-polarized quasiparticles in perovskite ferromagnet-insulator-superconductor ~F-I-S! heterostructures. Measurements ofâ€¦ (More)

By using different widths for two AlAs quantum wells comprising a bilayer system, we force the X-point conduction-band electrons in the two layers to occupy valleys with different Fermi contours,â€¦ (More)

Outliers are observations that depart from the pattern of the majority of the data. Identifying outliers is a major concern in data analysis because a few outliers, if left unchecked, can exert aâ€¦ (More)

We report measurements of the quantum Hall state energy gap at avoided crossings between Landau levels originating from different conduction band valleys in AlAs quantum wells. These gaps exhibit anâ€¦ (More)

The Projection Congruent Subset (PCS) is a new method for finding multivariate outliers. Like many other outlier detection procedures, PCS searches for a subset which minimizes a criterion. Theâ€¦ (More)
