3D Gravity and Chaos in CFTs with Fermions
Jan Boruch, Elisa Tabor, Gustavo J. Turiaci
Pure 3d gravity in AdS is believed to admit a holographic description in terms of 2d CFT. We introduce a theory of fermionic 3d gravity where we sum over geometries equipped with s…
Modular-invariant random matrix theory and AdS wormholes
Jan Boruch, Gabriele Di Ubaldo, Felix M. Haehl +2
We develop a non-perturbative definition of RMT: a generalization of random matrix theory that is compatible with the symmetries of two-dimensional conformal field theory. Gi…
Novel black saddles for 5d gravitational indices and the index enigma
Jan Boruch, Roberto Emparan, Luca V. Iliesiu +1
We construct a series of novel Euclidean multi-black-hole, black ring, black Saturn, and black lens solutions to supergravity that contribute as saddle-points to the grav…
Multicentered black hole saddles for supersymmetric indices
Jan Boruch, Luca V. Iliesiu, Sameer Murthy +1
The supersymmetric index in string theory can sometimes have a discontinuous integer-valued jump at co-dimension one surfaces in moduli space called walls of marginal stability. Wh…
The gravitational index of 5d black holes and black strings
Jan Boruch, Roberto Emparan, Luca V. Iliesiu +1
The supersymmetric index of 5d black strings and spinning black holes in M-theory is related to that of 4d black holes in type IIA supergravity when both theories are compactified…
