Classical defocussing of world lines -- Cosmological Implications
R Parthasarathy
We have extended our result on defocussing of world lines [1] by modifying gravity in the early epoch by a 5-d theory with scalar . The acceleration term in the Raychaudhuri…
Sudarshan Memorial Lecture
R Parthasarathy
In this invited talk, I discuss four important contributions of E.C.G. Sudarshan, among many. They are the V-A theory of weak interaction, Sudarshan - Glauber representation, tachy…
Classical Defocussing of world lines from Higher Dimensions
R. Parthasarathy, K. S. Viswanathan, Andrew DeBenedictis
A five-dimensional gravity theory, motivated by the brane-world picture, with Kaluza scalar in the 5 - dimensional metric as , is considered near t…
Photons with half-integral spin as q-Fermions
R. Parthasarathy, K. S. Viswanathan
The recently discovered 'light (photons) with half-integral spin' is interpreted as q-Fermions proposed by us in 1991, as these q-Fermions satisfy q-deformed anti-commutation relat…
Five dimensional Gravity and Big Bang Singularity
R. Parthasarathy
A 5-dimensional gravity theory, motivated by the brane world picture, with factorisable metric and with Kaluza scalar , is shown to give rise to a positive contribution…
Influence of Kaluza Scalar on the Raychaudhuri Equation
R. Parthasarathy
It is shown that the influence of Kaluza scalar is to induce expansion in the Raychaudhuri equation for two representative solutions of the Kaluza theory.
