Geometrically Induced Metastability and Holography

Geometric Metastability, Quivers and Holography

We use large N duality to study brane/anti-brane configurations on a class of CalabiYau manifolds. With only branes present, the Calabi-Yau manifolds in question give rise to N = 2 ADE quiver theories deformed by superpotential terms. We show that the large N duality conjecture of [1] reproduces correctly the known qualitative features of the brane/anti-brane physics. In the supersymmetric case...

Hysteresis During Stress-Induced Variant Rearrangement

This paper represents an attempt to understand, from basic principles, the origins of hysteresis during variant rearrangement. As a framework for this study, we focus on the biaxial loading experiments conducted in 171 on single crystals of 7; martensite, oriented so that two compound twinned variants of martensite have least energy. Our analysis supports the idea that hysteresis (at least in t...

Geometrical Finiteness, Holography, and the BTZ Black Hole

We show that the Euclidean BTZ black hole is a geometrically finite Kleinian manifold, with the topology of a solid torus. As a result of a theorem of Sullivan, the inequivalent hyperbolic structures of the black hole are parametrized by the Teichmüller parameters of its 2-torus boundary. These parameters may be interpreted as the mass and angular momentum of the black hole. The consequences of...

Surface oxides of the oxygen–copper system: Precursors to the bulk oxide phase?

To gain an initial understanding of the copper-based catalysts in commercially important chemical reactions such as the oxygenassisted water–gas shift reaction, we performed density-functional theory calculations, investigating the interaction of oxygen and copper, focusing on the relative stability of surface oxides and oxide surfaces of the O/Cu system. By employing the technique of ‘‘ab init...
