Gravitational energy-momentum pseudo-tensor in Palatini and metric gravity
H. Abedi, S. Capozziello, M. Capriolo +1
We derive the gravitational energy-momentum pseudo-tensor in both Palatini and metric approaches to gravity. We then obtain the related cosmological gravi…
Cosmological perturbations in gravitational energy-momentum complex
Habib Abedi, Amir M. Abbassi, Salvatore Capozziello
Starting from the energy-momentum of matter and gravitational field in the framework of General Relativity and Teleparallel Gravity, we obtain the energy-momentum complex in flat F…
F-term Inflation and RSII Brane Mode
M. Roostaee, Amir M. Abbassi
Considering hybrid F-term inflation in RSII model and using the most recent data from Planck 2018 and in comparison with Planck 2015and WMAP 9-year , we can obtain some interesting…
Hubble multi-scalar inflation
Habib Abedi, Amir M. Abbassi
Multiple field models of inflation exhibit new features than single field models. In this work, we study the hierarchy of parameters based on Hubble expansion rate in curved field…
Gravitational constant in multiple field gravity
Habib Abedi, Amir M. Abbassi
In the present study, we consider general form of the Lagrangian , that is a function of the Ricci scalar, multiple scalar fields and non-canonical kinetic terms.…
Gravitational Waves in a Spatially Closed deSitter Spacetime
Amir H. Abbassi, J. Khodagholizadeh, Amir M. Abbassi
Perturbation of gravitational fields may be decomposed into scalar,vector and tensor components.In this paper we concern with the evolution of tensor mode perturbations in a spatia…
