Spacetime as a deformable solid
M. O. Tahim, R. R. Landim, C. A. S. Almeida
In this letter we discuss the possibility of treating the spacetime by itself as a kind of deformable body for which we can define an fundamental lattice, just like atoms in crysta…

Generalized axion-photon couplings and dual descriptions on brane-worlds
M. O. Tahim, C. A. S. Almeida
In this work we obtain topological and dual theories on brane-worlds in several dimensions. Our brane is a solitonic-like hypersurface embedded in a space-time with a specific dime…

Topological Gravity, the Hierarchy Problem and Axion Physics
Carlos Alberto Santos Almeida, Makarius Oliveira Tahim
In the last years higher dimensional physics has won importance. Despite the Superstrings, higher dimensional effects, in measurable scales of energy (some TeV), became only possib…
