Wormholes require negative energy, and therefore an exotic matter source. Since Casimir’s energy is negative, it has been speculated as a good candidate to source those objects a long time ago. However, only very recently a full solution for 3+1 di

In this work we analyze the zero mode localization and resonances of 1/2-spin fermions in co-dimension one Randall-Sundrum braneworld scenarios. We consider deltalike, domain walls and deformed domain walls membranes. Beyond the in uence of the space

A new mechanism, valid for any smooth version of the Randall–Sundrum model, of getting localized massless vector field on the brane is described here. This is obtained by dimensional reduction of a five dimension massive two form, or Kalb–Ramond

What is the ultimate fate of something that falls into a black hole? From this question arises one of the most intricate problems of modern theoretical physics: the black hole information loss paradox. Bekenstein and Hawking have been shown that the

In this master's thesis we seek to discuss, in a clear, dialogical and systematic way, the techniques and consequences of the insertion of massive terms in Maxwell's Electromagnetic theory. Initially, we discuss Electromagnetism, usually worked out i

This work aims to present a methodology for the calculation of the angle of light deflection caused by agravitational field. This methodology consists in using the generalized Fermat principle for a space-time with spherical and static symmetry and

The Gödel scenario is a static and spatially homogeneous geometric structure of the universe – but not acceptable as it is absent from Hubble expansion – generated by the symmetrical and uniform rotation of dust-like source matter (moment densit

In this dissertation we study The Randall Sundrum models type I and II and the stabilization of the radius of the extra dimension. Both the types were elaborated by Lisa Randall and Ramman Sundrum. The type I was developed to solve the gauge hierarch
