WMAP constraints on low redshift evolution of dark energy
H. K. Jassal, J. S. Bagla, T. Padmanabhan
The conceptual difficulties associated with a cosmological constant have led to the investigation of alternative models in which the equation of state parameter, , of the da…
Stabilization of branes in a cosmological setting
H. K. Jassal
We study some cosmological consequences of the five dimensional, two brane Randall-Sundrum scenario. We integrate over the extra dimensions and in four dimensions the action reduce…
On brane cosmological solutions
H. K. Jassal
This paper presents some cosmological consequences of the five dimensional, two brane Randall-Sundrum brane scenario. The radius of the compact extra dimension is taken to be time…
Classical string propagation in gravitational fields
H. K. Jassal, A. Mukherjee
The motion of a string in curved spacetime is discussed in detail. The basic formalism for string motion in Minkowski spacetime and in curved spacetime is presented. The descriptio…
String propagation near Kaluza-Klein black holes: an analytical and numerical study
H. K. Jassal, A. Mukherjee
This paper presents a detailed investigation of the motion of a string near a Kaluza-Klein black hole, using the null string expansion. The zeroth-order string equations of motion…
