Dark Matter, Dark Energy and Rotation Curves
C. Sivaram, Venkata Manohara Reddy. A
Models for DM are invoked with various density distributions, to account for flat rotation curves of galaxies. The effect of DE on these profiles for large galaxies and clusters ar…
Torsion Gravity Effects on Charged-Particles and Neutron Interferometers
C. Sivaram, L. C. Garcia de Andrade
Torsion gravitational effects in the quantum interference of charged particles are investigated. The influence of axial torsion in the Schiff-Banhill effect (SB) inside a metallic…
Cosmic repulsion in presence of matter
G. Sudhakaran, C. Sivaram
A basic problem that confronts the standard cosmological models is the problem of initial singularity characterised by infinite material density, infinite temperature and infinite…
Torsion modified Plasma Screening in Astrophysics
C. Sivaram, L. C. Garcia de Andrade
The torsion modified Maxwell-Proca equations when applied to describe a plasma is shown to lead to a correction to the Debye screening length.For hot new born neutron stars the tor…
