Strong gravitational lensing—a probe for extra dimensions and KalbRamond field
Abstract
Strong field gravitational lensing in the context of both higher spacetime dimensions and in presence of KalbRamond field have been studied. After developing proper analytical tools to analyze the problem we consider gravitational lensing in three distinct black hole spacetimes—(a) four dimensional black hole in presence of KalbRamond field, (b) brane world black holes with KalbRamond field and finally (c) black hole solution in f ( T ) gravity. In all the three situations we have depicted the behavior of three observables: the asymptotic position approached by the relativistic images, the angular separation and magnitude difference between the outermost images with others packed inner ones, both numerically and analytically. Difference between these scenarios have also been discussed along with possible observational signatures.

KalbRamond gauge field theory, coupled to manifestly gaugeinvariant and reparametrizationinvariant secondquantized string fields, is studied. String condensation into the vacuum is shown to develop masses to the KalbRamond gauge field which we call the string Higgs mechanism. In case the KalbRamond field couples to the open strings which have a massless vector field in the spectrum, our field theory also exhibits the wellknown Stueckelberg mechanism. To strengthen our conclusion, we construct a lattice version of the above string field theory and demonstrate that the meanfield approximation indicates the existence of the Higgs phase.

Bulk KalbRamond field in the RandallSundrum scenario
We have considered the most general gauge invariant fivedimensional action of a second rank antisymmetric KalbRamond tensor gauge theory, including a topological term of the form {epsilon}{sup ABLMN}B{sub AB}H{sub LMN} in a RandallSundrum scenario. Such a tensor field B{sub AB} (whose rank3 field strength tensor is H{sub LMN}), which appears in the massless sector of a heterotic string theory, is assumed to coexist with the gravity in the bulk. The third rank field strength corresponding to the KalbRamond field has a wellknown geometric interpretation as the spacetime torsion. The only nontrivial classical solutions corresponding to the effective fourdimensional action aremore » 
KalbRamond field interactions in a braneworld scenario
Electromagnetic and (linearized) gravitational interactions of the KalbRamond (KR) field, derived from an underlying tendimensional heterotic string in the zero slope limit, are studied in a fivedimensional background RandallSundrum I spacetime with standard model fields confined to the visible brane having negative tension. The warp factor responsible for generating the gauge hierarchy in the Higgs sector is seen to appear inverted in the KR field couplings, when reduced to four dimensions. This leads to dramatically enhanced rotation, far beyond observational bounds, of the polarization plane of electromagnetic and gravitational waves, when scattered by a homogeneous KR background. Possible reasons formore » 
Solutions on a brane in a bulk spacetime with Kalb–Ramond field
Effective gravitational field equations on a brane have been derived, when the bulk spacetime is endowed with the second rank antisymmetric Kalb–Ramond field. Since both the graviton and the Kalb–Ramond field are closed string excitations, they can propagate in the bulk. After deriving the effective gravitational field equations on the brane, we solve them for a static spherically symmetric solution. It turns out that the solution so obtained represents a black hole or naked singularity depending on the parameter space of the model. The stability of this model is also discussed. Cosmological solutions to the gravitational field equations have beenmore » 
A direct probe of cosmological power spectra of the peculiar velocity field and the gravitational lensing magnification from photometric redshift surveys
The cosmological peculiar velocity field (deviations from the pure Hubble flow) of matter carries significant information on dark energy, dark matter and the underlying theory of gravity on large scales. Peculiar motions of galaxies introduce systematic deviations between the observed galaxy redshifts z and the corresponding cosmological redshifts z{sub c{sub o{sub s}}}. A novel method for estimating the angular power spectrum of the peculiar velocity field based on observations of galaxy redshifts and apparent magnitudes m (or equivalently fluxes) is presented. This method exploits the fact that a mean relation between z{sub c{sub o{sub s}}} and m of galaxies canmore »
