Entropy of 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…
The Hagedorn temperature in a decoupled sector of AdS/CFT
Troels Harmark, Kristjan R. Kristjansson, Marta Orselli
We match the Hagedorn/deconfinement temperature of planar N=4 super Yang-Mills (SYM) on R x S^3 to the Hagedorn temperature of string theory on AdS_5 x S^5. The match is done in a…
Non-perturbative Gravity, Hagedorn Bounce & CMB
Tirthabir Biswas, Robert Brandenberger, Anupam Mazumdar +1
In hep-th/0508194 it was shown how non-perturbative corrections to gravity can resolve the big bang singularity, leading to a bouncing universe. Depending on the scale of the non-p…
AdS/CFT v.s. String Loops
Gianluca Grignani, Marta Orselli, Bojan Ramadanovic +2
The one string-loop correction to the energies of two impurity BMN states are computed using IIB light-cone string field theory with an improved 3-string vertex that has been propo…
A Universality Test of the Quantum String Bethe Ansatz
Lisa Freyhult, Charlotte Kristjansen
We show that the quantum corrected string Bethe ansatz passes an important universality test by demonstrating that it correctly incorporates the non-analytical terms in the string…
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…
