Holographic Gravitational Anomalies
Per Kraus, Finn Larsen
In the AdS/CFT correspondence one encounters theories that are not invariant under diffeomorphisms. In the boundary theory this is a gravitational anomaly, and can arise in 4k+2 di…
Massless black holes and black rings as effective geometries of the D1-D5 system
Vijay Balasubramanian, Per Kraus, Masaki Shigemori
We compute correlation functions in the AdS/CFT correspondence to study the emergence of effective spacetime geometries describing complex underlying microstates. The basic argumen…
Microscopic Black Hole Entropy in Theories with Higher Derivatives
Per Kraus, Finn Larsen
We discuss higher derivative corrections to black hole entropy in theories that allow a near horizon AdS_3 x X geometry. In arbitrary theories with diffeomorphism invariance we sho…
R^2 Corrections to Black Ring Entropy
Iosif Bena, Per Kraus
Recently, Guica, Huang, Li, and Strominger considered an R^2 correction to the entropy of a black ring, and found a mismatch between supergravity and the CFT. However, such a compa…
Black Rings in Taub-NUT
Iosif Bena, Per Kraus, Nicholas P. Warner
We construct the most generic three-charge, three-dipole-charge, BPS black-ring solutions in a Taub-NUT background. These solutions depend on seven charges and six moduli, and inte…
Attractors and Black Rings
Per Kraus, Finn Larsen
The attractor mechanism is usually thought of as the fixing of the near horizon moduli of a BPS black hole in terms of conserved charges measured at infinity. Recent progress in un…
Microstates of the D1-D5-KK System
Iosif Bena, Per Kraus
We find supergravity solutions corresponding to all U(1) x U(1) invariant chiral primaries of the D1-D5-KK system. These solutions are 1/8 BPS, carry angular momentum, and are asym…
