In this paper we apply the five-dimensional $f(T)$ gravity with $f(T)=T+k
T^n$ to brane scenario to explore the solutions under a given warp factor, and
we find that the analytic domain wall solution will be a double-kink solution
when the geometric effect of spacetime torsion is strongly enhanced. We also
investigate the localization of fermion fields on the split branes
corresponding to the double-kink solution.

    • "A brane model in the Recently presented EiBI gravity theory were constructed in Ref. [24] and it was found that the four-dimensional Einstein gravity can be recovered on the brane at low energy. Branes in spacetime with torsion were investigated – 1 – in Ref [25] [26] and it was shown that in the f (T ) gravity that the torsion of spacetime can effect the inner structure of branes [25]. Reference [27] investigated braneworld teleparallel gravity. "

    ABSTRACT: Recently, Lü and Pope proposed critical gravities in [Phys. Rev. Lett. 106, 181302 (2011)]. In this paper we construct analytic brane solutions in critical gravity with matter. The Gibbons-Hawking surface term and junction condition are investigated, and the thin and thick brane solutions are obtained. All these branes are embedded in five-dimensional anti-de Sitter spacetimes. Our solutions are stable against scalar perturbations, and the zero modes of scalar perturbations cannot be localized on the branes.

    • "In special cases, where the membranes are generated by scalar fields, its is very simple to obtain solutions through the superpotential method. In particular, several membrane types were considered: those generated by models with more than one scalar fields, deformed membranes and so on [3] [4] [5] [6] [7] [8] [9]. Beyond that, the analysis of how the localization is made for various fields (tensors and spinors) have been understood [10] [11] [12] [13] [14] [15] [16] [17]. "

    ABSTRACT: The transfer matrix method is used to analyze resonances in Randall-Sundrum models. Although it has successfully been used previously by us we provide here a comparison between the numerical and analytical models. To reach this we first find new exact solution for the scalar, gauge, Kalb-Ramond and $q-$form fields. Them we calculate numerically the resonances by the transfer matrix method and compare with the analytical result. For completeness, this is done for models with and without the dilaton coupling. The results show a perfect agreement between the analytical and numerical methods.

    ABSTRACT: We consider $f(T)$ gravity for a Weitzenbock spherically symmetric and static spacetime, where the metric is projected in the tangent space to the manifold for a set of non-diagonal tetrads. The matter content is coupled through the energy momentum tensor of an anisotropic fluid, generating various classes of new black hole and wormhole solutions. One of these classes is that of cold black holes. We also perform the reconstruction scheme of the algebraic function $f(T)$ for two cases where the radial pressure is proportional to $f(T)$ and its first derivative.
