Bloch Waves and Fuzzy Cylinders: 1/4-BPS Solutions of Matrix Theory
Peter G. Shepard
In this note, we present a broad class of quarter-BPS solutions to matrix theory, corresponding to non-commutative cylinders of arbitrary cross-sectional profile in R^8. The soluti…

Black Hole Statistics from Holography
Peter G. Shepard
We study the microstates of the ``small'' black hole in the $\half$-BPS sector of AdS, the superstar of Myers and Tafjord, using the powerful holographic description…

Topology Changing Transitions in Bubbling Geometries
Petr Horava, Peter G. Shepard
Topological transitions in bubbling half-BPS Type IIB geometries with SO(4) x SO(4) symmetry can be decomposed into a sequence of n elementary transitions. The half-BPS solution th…
