Mixed Moments for the Product of Ginibre Matrices
Nick Halmagyi, Shailesh Lal
We study the ensemble of a product of n complex Gaussian i.i.d. matrices. We find this ensemble is Gaussian with a variance matrix which is averaged over a multi-Wishart ensemble.…
Tensor Models for Black Hole Probes
Nick Halmagyi, Swapnamay Mondal
The infrared dynamics of the SYK model, as well as its associated tensor models, exhibit some of the non trivial features expected of a holographic dual of near extremal black hole…
On the On-Shell: The Action of AdS Black Holes
Nick Halmagyi, Shailesh Lal
We compute the on-shell action of static, BPS black holes in AdS from gauged supergravity coupled to vector multiplets and show that it is equal to minus the entro…
Heterotic Hyper-Kahler Flux Backgrounds
Nick Halmagyi, Dan Israel, Matthieu Sarkis +1
We study Heterotic supergravity on Hyper-Kahler manifolds in the presence of non-trivial warping and three form flux with Abelian bundles in the large charge limit. We find exact,…
The Abelian Heterotic Conifold
Nick Halmagyi, Dan Israel, Eirik Eik Svanes
We study heterotic supergravity on the conifold and its Z2 orbifold with Abelian gauge fields and three-form flux. At large distances, these solutions are locally Ricci-flat, have…
Quarter-BPS Black Holes in AdS-NUT from Gauged Supergravity
Harold Erbin, Nick Halmagyi
We study gauged supergravity with gauge group coupled to vector multiplets and find quite general analytic solutions for quarter-BPS black holes with mass, NUT a…
