Small Black Holes on Cylinders
Troels Harmark
We find the metric of small black holes on cylinders, i.e. neutral and static black holes with a small mass in d-dimensional Minkowski-space times a circle. The metric is found usi…
Phase Structure of Black Holes and Strings on Cylinders
T. Harmark, N. A. Obers
We use the (M,n) phase diagram recently introduced in hep-th/0309116 to investigate the phase structure of black holes and strings on cylinders. We first prove that any static neut…
New Phase Diagram for Black Holes and Strings on Cylinders
T. Harmark, N. A. Obers
We introduce a novel type of phase diagram for black holes and black strings on cylinders. The phase diagram involves a new asymptotic quantity called the relative binding energy.…
Black Holes and Black Strings on Cylinders
T. Harmark, N. A. Obers
We review the recently discovered ansatz that describes non-extremal charged dilatonic branes of string/M-theory with a transverse circle. The ansatz involves a new coordinate syst…
Supersymmetric Godel Universes in String Theory
Troels Harmark, Tadashi Takayanagi
Supersymmetric backgrounds in string and M-theory of the Godel Universe type are studied. We find several new Godel Universes that preserve up to 20 supersymmetries. In particular,…
