The Phase Structure of Higher-Dimensional Black Rings and Black Holes
Roberto Emparan, Troels Harmark, Vasilis Niarchos +2
We construct an approximate solution for an asymptotically flat, neutral, thin rotating black ring in any dimension D>=5 by matching the near-horizon solution for a bent boosted bl…
Tree-Level Stability Without Spacetime Fermions: Novel Examples in String Theory
Dan Israel, Vasilis Niarchos
Is perturbative stability intimately tied with the existence of spacetime fermions in string theory in more than two dimensions? Type 0'B string theory in ten-dimensional flat spac…
Orientifolds in N=2 Liouville Theory and its Mirror
Dan Israel, Vasilis Niarchos
We consider unoriented strings in the supersymmetric SL(2,R)/U(1) coset, which describes the two-dimensional Euclidean black hole, and its mirror dual N=2 Liouville theory. We anal…
Instabilities of Black Strings and Branes
Troels Harmark, Vasilis Niarchos, Niels A. Obers
We review recent progress on the instabilities of black strings and branes both for pure Einstein gravity as well as supergravity theories which are relevant for string theory. We…
