Non-Supersymmetric Attractor Flow in Symmetric Spaces
Davide Gaiotto, Wei Li, Megha Padi
We derive extremal black hole solutions for a variety of four dimensional models which, after Kaluza-Klein reduction, admit a description in terms of 3D gravity coupled to a sigma…
Genus Two Partition Functions of Extremal Conformal Field Theories
Davide Gaiotto, Xi Yin
Recently Witten conjectured the existence of a family of "extremal" conformal field theories (ECFTs) of central charge c=24k, which are supposed to be dual to three-dimensional pur…
Notes on Superconformal Chern-Simons-Matter Theories
Davide Gaiotto, Xi Yin
The three dimensional N=2 supersymmetric Chern-Simons theory coupled to matter fields, possibly deformed by a superpotential, give rise to a large class of exactly conformal theori…
Black Hole Deconstruction
Frederik Denef, Davide Gaiotto, Andrew Strominger +2
A D4-D0 black hole can be deconstructed into a bound state of D0 branes with a D6-anti-D6 pair containing worldvolume fluxes. The exact spacetime solution is known and resembles a…
Comments on the Spectrum of CHL Dyons
Atish Dabholkar, Davide Gaiotto, Suresh Nampuri
We address a number of puzzles relating to the proposed formulae for the degeneracies of dyons in orbifold compactifications of the heterotic string to four dimensions with …
Examples of M5-Brane Elliptic Genera
Davide Gaiotto, Xi Yin
We determine the modified elliptic genus of an M5-brane wrapped on various one modulus Calabi-Yau spaces, using modular invariance together with some known Gopakumar-Vafa invariant…
