Probing the Effects of Lorentz-Symmetry Violating Chern-Simons and Ricci-Cotton Terms in Higher Derivative Gravity
B. Pereira-Dias, C. A. Hernaski, J. A. Helayël-Neto
The combined effects of the Lorentz-symmetry violating Chern-Simons and Ricci-Cotton actions are investigated for the Einstein-Hilbert gravity in the second order formalism modifie…
Chern-Simons Gravity with (Curvature)- and (Torsion)-Terms and A Basis of Degree-of-Freedom Projection Operators
J. A. Helayël-Neto, C. A. Hernaski, B. Pereira-Dias +2
We investigate the effects of (Curvature)- and (Torsion)- terms in the Einstein-Hilbert-Chern-Simons Lagrangian. The purposes are two-fold: (i) to show the efficacy of…
Extending the Spin Projection Operators for Gravity Models with Parity-Breaking in 3-D
C. A. Hernaski, B. Pereira-Dias, A. A. Vargas-Paredes
We propose a new basis of spin-operators, specific for the case of planar theories, which allows a Lagrangian decomposition into spin-parity components. The procedure enables us to…
