Magnetic Heisenberg-chain/pp-wave correspondence
Troels Harmark, Kristjan R. Kristjansson, Marta Orselli
We find a decoupling limit of planar N=4 super Yang-Mills (SYM) on R x S^3 in which it becomes equivalent to the ferromagnetic XXX_{1/2} Heisenberg spin chain in an external magnet…
Three-Charge Black Holes on a Circle
Troels Harmark, Kristjan R. Kristjansson, Niels A. Obers +1
We study phases of five-dimensional three-charge black holes with a circle in their transverse space. In particular, when the black hole is localized on the circle we compute the c…
Global geometry of two-dimensional charged black holes
Andrei V. Frolov, Kristjan R. Kristjansson, Larus Thorlacius
The semiclassical geometry of charged black holes is studied in the context of a two-dimensional dilaton gravity model where effects due to pair-creation of charged particles can b…
