In this paper, the gravitational deflection of relativistic massive particles up to the second post-Minkowskian order by static and spherically symmetric wormholes is investigated in the weak-field limit. These wormholes include the Janis-Newman-Winicour wormhole, a class of zero Ricci scalar scalar-tensor wormholes, and a class of charged Einstein-Maxwell-dilaton wormholes. With the Jacobi metric approach, the Gauss-Bonnet theorem is employed to study the gravitational deflection. In this scheme, the deflection angle as a topological effect is considered. Moreover, we analyze the influence of the spacetime parameters on the results. PACS numbers: 98.62.Sb, 95.30.Sf

“…As far as we know, this is the simplest wormhole solution found in EiBI gravity. In [36], Jusufi also obtained a static and asymptotically conical wormhole, but in the GR context. For this, he considered the minimal coupling of the GM tensor (T µ ν = diag −η 2 /r 2 , −η 2 /r 2 , 0, 0 to the gravity plus an anisotropic fluid.…”

Nonlinear σ -models in the Eddington-inspired Born-Infeld gravity

In this paper we consider two different nonlinear σ-models minimally coupled to Eddington-inspired Born-Infeld gravity. We show that the resultant geometries represent minimal modifications with respect to those found in GR, though with important physical consequences. In particular, wormhole structures always arise, though this does not guarantee by itself the geodesic completeness of those space-times. In one of the models, quadratic in the canonical kinetic term, we identify a subset of solutions which are regular everywhere and are geodesically complete. We discuss characteristic features of these solutions and their dependence on the relationship between mass and global charge.

“…In stationary spacetime, the optical metric (or Jacobi metric) is a Randers-Finsler metric. However, in these cases one can use the osculating Riemannian metric by Werner's method [14] or use Jusufi's method to avoid the Finsler metric [60].…”

Equivalence of Gibbons-Werner method to geodesics method in the study of gravitational lensing

The Gibbons-Werner method where the Gauss-Bonnet theorem is applied to study the gravitational deflection angle has received much attention recently. In this paper, we study the equivalence of the Gibbons-Werner method to the standard geodesics method, and it is shown that the geodesics method can be derived with the Gibbons-Werner method, for asymptotically flat case. In the geodesics method, the gravitational deflection angle of particle depends entirely on the geodesic curvature of the particle ray in the Euclidean space. The gravitational deflection of light in Kerr-Newman spacetime is calculated by different technologies under the Gibbons-Werner framework, as an intuitive example to show the equivalence.
