Scalaron excitation by topological vortices in quadratic gravity on a BTZ black hole background
C. A. S. Almeida, F. C. E. Lima
In three spacetime dimensions, pure Einstein gravity admits no local propagating degrees of freedom, yet nontrivial gravitational backgrounds such as the BTZ black hole provide a n…

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…
