Gravitational bending angle with finite distances by Casimir wormholes

نویسندگان

چکیده

In this paper, we investigate the gravitational bending angle due to Casimir wormholes, which consider energy as source. Furthermore, some of these wormholes regard Generalized Uncertainty Principle (GUP) corrections energy. We use Ishihara method for Jacobi metric, allows us study light and massive test particles finite distances. Beyond uncorrected source, many GUP corrections, namely, Kempf, Mangano Mann (KMM) model, Detournay, Gabriel Spindel (DGS) so-called type II model principle. also find deflection in case receiver source are far away from lens. case, compute optical scalars: convergence shear a weak Our self-consistent iterative calculations indicate by previous paper.

Gravitational lensing by wormholes

We have investigated the gravitational lensing by two wormholes, viz., Janis Newman-Winnicour (JNW) wormhole and Ellis wormhole. The deflection angle in the strong field limit is calculated and various lens parameters of two wormholes are compared. It is shown that the JNW wormhole exhibits the relativistic images, while the Ellis wormhole does not have any relativistic images due to the absenc...

Gravitational Lensing by Wormholes

Abstract. Natural wormholes and its astrophysical signatures have been sugested in various oportunities. By applying the strong field limit of gravitational lensing theory, we calculate the deflection angle produced by Morris-Thorne wormholes in asimptotically flat space-times. The results show that wormholes act like convergent lenses. Therefore it is hard to distinguish them from black holes ...

Gravitational memory of natural wormholes

A traversable wormhole solution of general scalar–tensor field equations is presented. We have shown, after a numerical analysis for the behavior of the scalar field of Brans-Dicke theory, that the solution is completely singularity– free. Furthermore, the analysis of more general scalar field dependent coupling constants indicates that the gravitational memory phenomenon may play an important ...

Gravitational Casimir effect.

We derive the gravitonic Casimir effect with nonidealized boundary conditions. This allows the quantification of the gravitonic contribution to the Casimir effect from real bodies. We quantify the meagerness of the gravitonic Casimir effect in ordinary matter. We also quantify the enhanced effect produced by the speculated Heisenberg-Couloumb (HC) effect in superconductors, thereby providing a ...

Gravitational Bending of Light with Frequency Shifts

Non-static gravitational fields generally introduce frequency shifts when bending light. In this paper, I discuss the frequency shifts induced in the bending of light by moving masses. As examples, I treat the recently discovered high-velocity pulsar PSR 2224+65 and a typical Einstein ring. PACS Numbers: 97.60Gb, 97.60Jd The four Jupiter probes Pioneers 10, 11 and Voyagers 1,2 have all reached ...
