Electrified BPS Giants: BPS configurations on Giant Gravitons with Static Electric Field
M. Ali-Akbari, M. M. Sheikh-Jabbari
We consider D3-brane action in the maximally supersymmetric type IIB plane-wave background. Upon fixing the light-cone gauge, we obtain the light-cone Hamiltonian which is manifest…
Lovelock Gravity at the Crossroads of Palatini and Metric Formulations
Q. Exirifard, M. M. Sheikh-Jabbari
We consider extensions of the Einstein-Hilbert Lagrangian to a general functional of metric and Riemann curvature tensor. A given such Lagrangian describes two different theories d…
An N-tropic Solution to the Cosmological Constant Problem
M. M. Sheikh-Jabbari
Based on the assertion that the cosmological constant problem is essentially a quantum gravity problem, the framework which addresses the cosmological constant problem should also…
Non-Abelian Magnetized Blackholes and Unstable Attractors
A. E. Mosaffa, S. Randjbar-Daemi, M. M. Sheikh-Jabbari
Fluctuations of non-Abelian gauge fields in a background magnetic flux contain tachyonic modes and hence the background is unstable. We extend these results to the cases where the…
Gravi-Leptogenesis: Leptogenesis from Gravity Waves in Pseudo-scalar Driven Inflation Models
S. H. Alexander, M. Peskin, M. M. Sheikh-Jabbari
In this talk we present a mechanism for leptogenesis which is based on gravity waves produced during inflation. We show that when inflation is driven by a pseudo-scalar field the m…
