On the "Universal" Quantum Area Spectrum
A. J. M. Medved
There has been much debate over the form of the quantum area spectrum for a black hole horizon, with the evenly spaced conception of Bekenstein having featured prominently in the d…
De-Sitter nonlinear sigma model and accelerating universe
Joohan Lee, Tae Hoon Lee, Taeyoon Moon +1
We consider a cosmology with a non-compact nonlinear sigma model.The target space is of de-Sitter type and four scalar fields are introduced.The potential is absent but cosmologica…
A Commentary on Ruppeiner Metrics for Black Holes
A. J. M. Medved
There has been some recent controversy regarding the Ruppeiner metrics that are induced by Reissner-Nordstrom (and Reissner-Nordstrom-like) black holes. Most infamously, why does t…
Higher dimensional cosmological model with a phantom field
S. T. Hong, J. Lee, T. H. Lee +1
We consider a higher dimensional gravity theory with a negative kinetic energy scalar field and a cosmological constant. We find that the theory admits an exact cosmological soluti…
