A note on spherically symmetric naked singularities in general dimension
Peter Langfelder, Robert B. Mann
We discuss generalizations of the recent theorem by Dafermos (hep-th/0403033) forbidding a certain class of naked singularities in the spherical collapse of a scalar field. Employi…
Geons with spin and charge
Jorma Louko, Robert B. Mann, Donald Marolf
We construct new geon-type black holes in D>3 dimensions for Einstein's theory coupled to gauge fields. A static nondegenerate vacuum black hole has a geon quotient provided the sp…
On the Tensor/Scalar Ratio in Inflation with UV Cutoff
A. Ashoorioon, R. B. Mann
Anisotropy of the cosmic microwave background radiation (CMB) originates from both tensor and scalar perturbations. To study the characteristics of each of these two kinds of pertu…
Dynamical Charged N-body Equilibrium in Circular Dilaton Gravity
Ryan Kerner, Robert B. Mann
We extend the problem of circular dilaton gravity to include charged particles. We examine the two (charged) particle case in detail and find an exact equilibrium solution.…
Generation of Cosmological Seed Magnetic Fields from Inflation with Cutoff
Amjad Ashoorioon, Robert B. Mann
Inflation has the potential to seed the galactic magnetic fields observed today. However, there is an obstacle to the amplification of the quantum fluctuations of the electromagnet…
