Gravity: A new gravity framework

Mahmoud AlHallak

In this work we present a new framework of the gravity sector by considering the extension , in which is the Ricci scalar and is the equation of state. Three differ…

Warm Affine Inflation

Mahmoud AlHallak

The warm inflationary scenario is investigated in the context of affine gravity formalism. A general framework is provided for studying different single-field potentials. Using the…

Salvaging Power-Law Inflation through Warming

M. Alhallak, N. Chamoun, M. S. Eldaher

Power-Law inflation with scale factor is investigated in the context of warm inflation. The treatment is performed in the weak and strong dissipation limits. In add…

On Warm Natural Inflation and Planck 2018 constraints

Mahmoud AlHallak, Khalil Kalid Al Said, Nidal Chamoun +1

We investigate Natural Inflation with non-minimal coupling to gravity, characterized either by a quadratic or a periodic term, within the Warm Inflation paradigm during the slow ro…

Natural Inflation with non minimal coupling to gravity in gravity under the Palatini formalism

M. AlHallak, N. Chamoun, M. S. Eldaher

Natural Inflation with non-minimal coupling (NMC) to gravity, embodied by a Lagrangian term , is investigated in the context of an extended gravity of the form .…

Palatini gravity and variants of k-/constant roll/warm inflation within variation of strong coupling scenario

M. AlHallak, A. AlRakik, N. Chamoun +1

We show that upon applying Palatini , characterized by an $\a R^2$-term, within a scenario motivated by a temporal variation of strong coupling constant, then one gets a quad…

Realization of Power-Law Inflation & Variants via Variation of the Strong Coupling Constant

M. AlHallak, N. Chamoun

We present a model of power law inflation generated by variation of the strong coupling constant. We then extend the model to two varying coupling constants which leads to a potent…
