Warped Radion Inflation
Joel Trudeau, James M. Cline
We show that the radion in a warped geometry bounded by two branes can have a potential suitable for inflation. Our construction is based upon a solution known in string theory as…
Conical Defects in Higher Spin Theories
Alejandra Castro, Rajesh Gopakumar, Michael Gutperle +1
We study conical defect geometries in the SL(N) Chern-Simons formulation of higher spin gauge theories in AdS_3. We argue that (for N\geq 4) there are special values of the deficit…
The Gravity Dual of the Ising Model
Alejandra Castro, Matthias R. Gaberdiel, Thomas Hartman +2
We evaluate the partition function of three dimensional theories of gravity in the quantum regime, where the AdS radius is Planck scale and the central charge is of order one. The…
Towards the fast scrambling conjecture
Nima Lashkari, Douglas Stanford, Matthew Hastings +2
Many proposed quantum mechanical models of black holes include highly nonlocal interactions. The time required for thermalization to occur in such models should reflect the relaxat…
Black Holes and Singularity Resolution in Higher Spin Gravity
Alejandra Castro, Eliot Hijano, Arnaud Lepage-Jutier +1
We investigate higher spin theories of gravity in three dimensions based on the gauge group SL(N,R)*SL(N,R). In these theories the usual diffeomorphism symmetry is enhanced to incl…
Noncommutative Vortices and Instantons from Generalized Bose Operators
Nirmalendu Acharyya, Nitin Chandra, Sachindeo Vaidya
Generalized Bose operators correspond to reducible representations of the harmonic oscillator algebra. We demonstrate their relevance in the construction of topologically non-trivi…
