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…
Dirac quantization of a nonminimal gauged O(3) sigma model
K. C. Mendes, R. R. Landim, C. A. S. Almeida
The (2+1) dimensional gauged O(3) nonlinear sigma model with Chern-Simons term is canonically quantized. Furthermore, we study a nonminimal coupling in this model implemented by me…
Topologically massive nonabelian BF models in arbitrary space-time dimensions
R. R. Landim, C. A. S. Almeida
This work extends to the D-dimensional space-time the topological mass generation mechanism of the nonabelian BF model in four dimensions. In order to construct the gauge invariant…
