Single crystals of GaN < 3 mm in length were grown by sublimation/recondensation of GaN in 760 Torr ▫$NH_3$▫ at 1100°C. Platelets of AlN < 1 mm thick were similarly grown between 1950 and 2250°C using an Al source. Monocrystalline GaN and ▫$Al_xGa_{1-x}N$▫(0001)(0.05 < x < 0.96) films were grown via ...

We present explicit solutions of the time-symmetric initial value constraints, expressed in terms of freely specifiable harmonic functions for examples of supergravity theories, which emerge as effective theories of compactified string theory. These results are a prerequisite for the study of the ti ...

We present three families of exact, cohomogeneity-one Einstein metrics in (2n + 2) dimensions, which are generalizations of the Stenzel construction of Ricci-flat metrics to those with a positive cosmological constant. The first family of solutions are Fubini-Study metrics on the complex projective ...

We study the vacuum polarization of a massless minimally coupled scalar field at the horizon of four-charge STU black holes. We compare the results for the standard asymptotically flat black holes and for the black holes obtained in the "subtracted limit", both in the general static case and at the ...

External magnetic fields can probe the composite structure of black holes in string theory. With this motivation we study magnetised four-charge black holes in the STU model, a consistent truncation of maximally supersymmetric supergravity with four types of electromagnetic fields. We employ solutio ...
