D-Dimensional Log Gravity
Mohsen Alishahiha, Reza Fareghbal
We study Einstein gravity in dimensions modified by curvature squared at critical point where the theory contains only massless gravitons. We show that at the critical po…
Fields Annihilation and Particles Creation in DBI inflation
Hassan Firouzjahi, Salomeh Khoeini-Moghaddam
We consider a model of DBI inflation where two stacks of mobile branes are moving ultra relativistically in a warped throat. The stack closer to the tip of the throat is annihilate…
Light-Like Noncommutativity, Light-Front Quantization and New Light on UV/IR Mixing
M. M. Sheikh-Jabbari, A. Tureanu
We revisit the problem of quantizing field theories on noncommutative Moyal spacetime with \emph{light-like} noncommutativity. To tackle the issues arising from noncommuting and he…
Beyond Logarithmic Corrections to Cardy Formula
F. Loran, M. M. Sheikh-Jabbari, M. Vincon
As shown by Cardy modular invariance of the partition function of a given unitary non-singular 2d CFT with left and right central charges c_L and c_R, implies that the density of s…
Constraint structure of the three dimensional massive gravity
M. Sadegh, A. Shirzad
Constraint analysis of the three-dimensional massive gravity, the so- called new massive gravity, is studied in the Palatini formalism. We show that amongst 6 components of the met…
Orientifolded Locally AdS3 Geometries
F. Loran, M. M. Sheikh-Jabbari
Continuing the analysis of [arXiv:1003.4089[hep-th]], we classify all locally AdS3 stationary axi-symmetric unorientable solutions to AdS3 Einstein gravity and show that they are o…
