Scalar fields and three-point functions in D=3 higher spin gravity
Martin Ammon, Per Kraus, Eric Perlmutter
We compute boundary three-point functions involving two scalars and a gauge field of arbitrary spin in the AdS vacuum of Vasiliev's higher spin gravity, for any deformation paramet…
On Stability and Transport of Cold Holographic Matter
Martin Ammon, Johanna Erdmenger, Shu Lin +3
We use gauge-gravity duality to study the stability of zero-temperature, finite baryon density states of N=4 supersymmetric SU(Nc) Yang-Mills theory coupled to a single massive fun…
Spacetime Geometry in Higher Spin Gravity
Martin Ammon, Michael Gutperle, Per Kraus +1
Higher spin gravity is an interesting toy model of stringy geometry. Particularly intriguing is the presence of higher spin gauge transformations that redefine notions of invarianc…
Black Hole Instability Induced by a Magnetic Field
Martin Ammon, Johanna Erdmenger, Patrick Kerner +1
In the context of gauge/gravity duality, we find a new black hole instability in asymptotically AdS spaces. On the field theory side, this instability is induced by a magnetic fiel…
