Cosmic acceleration via derivative matter couplings
Zahra Haghani, Shahab Shahidi
A gravitational theory with derivative matter coupling is proposed which adopt de Sitter expansion at late times with ordinary baryonic matter. Matter components are conserved sepa…
Cosmology of a higher derivative scalar theory with non-minimal Maxwell coupling
Shahab Shahidi
Higher derivative scalar field theory in curved space-time belongs to the GLPV theory coupled non-minimally to the Maxwell field is considered. We will show that the theory admits…
Reply to "Comment on 'Can accretion disk properties observationally distinguish black holes from naked singularities?'"
Zoltán Kovács, Tiberiu Harko, Shahab Shahidi
In the Comment on "Can accretion disk properties observationally distinguish black holes from naked singularities?", by Bertrand Chauvineau, Phys. Rev. D {\bf 98}, 088501 (2018), t…
Modified gravity one-loop partition function
Shahab Shahidi, Farid Charmchi, Zahra Haghani +1
The one-loop partition function of the gravity theory is obtained around AdS background. After suitable choice of the gauge condition and computation of the…
Axionic extension of the Proca action
Shahab Shahidi
In the context of Cartan theory, we will show that the Proca action can be obtained from the Gauss-Bonnet action for a special choice of the torsion tensor. This in fact equivalent…
