Tachyon with an inverse power-law potential in a braneworld cosmology
Neven Bilić, Silvije Domazet, Goran S. Djordjevic
We study a tachyon cosmological model based on the dynamics of a 3-brane in the bulk of the second Randall-Sundrum model extended to more general warp functions. A well known proto…
A photon propagator on de Sitter in covariant gauges
Silvije Domazet, Tomislav Prokopec
We construct a de Sitter invariant photon propagator in general covariant gauges. Our result is a natural generalization of the Allen-Jacobson photon propagator in Feynman gauge. O…
Renormalization group scale-setting from the action - a road to modified gravity theories
Silvije Domazet, Hrvoje Stefancic
The renormalization group (RG) corrected gravitational action in Einstein-Hilbert and other truncations is considered. The running scale of the renormalization group is treated as…
On analytical solutions of f(R) modified gravity theories in FLRW cosmologies
Silvije Domazet, Voja Radovanovic, Marko Simonovic +1
A novel analytical method for f(R) modified theories without matter in Friedmann-Lemaitre-Robertson-Walker spacetimes is introduced. The equation of motion for the scale factor in…
Renormalization group scale-setting in astrophysical systems
Silvije Domazet, Hrvoje Stefancic
A more general scale-setting procedure for General Relativity with Renormalization Group corrections is proposed. Theoretical aspects of the scale-setting procedure and the interpr…
