Gravitational Redshift in Einstein-Kalb-Ramond Spacetime and Randall-Sundrum Scenario
Soumitra SenGupta, Saurabh Sur
It is shown that the gravitational redshift as predicted by Einstein's theory, is modified in presence of second rank antisymmetric tensor (Kalb-Ramond) field in a string inspired…
Static spherisymmetric solutions, gravitational lensing and perihelion precession in Einstein--Kalb--Ramond theory
Sayan Kar, Soumitra SenGupta, Saurabh Sur
Static, spherically symmetric solutions of the Einstein--Kalb--Ramond (KR) field equations are obtained. Besides an earlier known exact solution, we also find an approximate, asymp…
Parity violation in four and higher dimensional spacetime with torsion
Biswarup Mukhopadhyaya, Somasri Sen, Soumitra SenGupta +1
The possibility of parity violation in a gravitational theory with torsion is extensively explored in four and higher dimensions. In the former case,we have listed our conclusions…
Does curvature-dilaton coupling with Kalb Ramond field lead to an accelerating Universe ?
Soumitra SenGupta, Saurabh Sur
In this work we show that the Universe evolving in a spacetime with torsion (originated from a second rank antisymmetric Kalb-Ramond field) and dilaton is free from any big bang si…
Cosmic optical activity from an inhomogeneous Kalb-Ramond field
Sayan Kar, Parthasarathi Majumdar, Soumitra SenGupta +1
The effects of introducing a harmonic spatial inhomogeneity into the Kalb-Ramond field, interacting with the Maxwell field according to a `string-inspired' proposal made in earlier…
Spacetime torsion and parity violation: a gauge invariant formulation
Biswarup Mukhopadhyaya, Soumitra SenGupta, Saurabh Sur
The possibility of parity violation through spacetime torsion has been explored in a scenario containing fields with different spins. Taking the Kalb-Ramond field as the source of…
