New Taub-NUT-Reissner-Nordström spaces in higher dimensions
Robert B. Mann, Cristian Stelea
We construct new charged solutions of the Einstein-Maxwell field equations with cosmological constant. These solutions describe the nut-charged generalisation of the higher dimensi…
Ghost Condensation in the Brane-World
Robert B. Mann, John J. Oh
Motivated by the ghost condensate model, we study the Randall-Sundrum (RS) brane-world with an arbitrary function of the higher derivative kinetic terms, , where $X…
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…
A physical basis for the phase in Feynman path integration
G. N. Ord, J. A. Gualtieri, R. B. Mann
In the path integral formulation of quantum mechanics, the phase factor Exp[iS(x[t])] is associated with every path x[t]. Summing this factor over all paths yields Feynman's propag…
Minimum Length Cutoff in Inflation and Uniqueness of the Action
A. Ashoorioon, A. Kempf, R. B. Mann
According to most inflationary models, fluctuations that are of cosmological size today started out much smaller than any plausible cutoff length such as the string or Planck lengt…
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…
