Inflaton candidates: from string theory to particle physics
K. Sravan Kumar
Cosmic inflation is the cornerstone of modern cosmology. In particular, following the Planck mission reports presented in 2015 regarding cosmic microwave background (CMB), there is…
Towards nonsingular rotating compact object in ghost-free infinite derivative gravity
Luca Buoninfante, Alan S. Cornell, Gerhard Harmsen +4
The vacuum solution of Einstein's theory of general relativity provides a rotating metric with a ring singularity, which is covered by the inner and outer horizons, and an ergo reg…
Conformally-flat, non-singular static metric in infinite derivative gravity
Luca Buoninfante, Alexey S. Koshelev, Gaetano Lambiase +2
In Einstein's theory of general relativity the vacuum solution yields a blackhole with a curvature singularity, where there exists a point-like source with a Dirac delta distributi…
Kinetic inflation in deformed phase space Brans-Dicke cosmology
S. M. M. Rasouli, J. Marto, P. V. Moniz
In this paper, by establishing a Brans-Dicke (BD) cosmology by means of a deformed phase space, in the absence of any scalar potential, cosmological constant and ordinary matter, w…
Inflationary Universe in Deformed Phase Space Scenario
S. M. M. Rasouli, N. Saba, M. Farhoudi +2
We consider a noncommutative (NC) inflationary model with a homogeneous scalar field minimally coupled to gravity. The particular NC inflationary setting produces entirely new cons…
Towards resolution of anisotropic cosmological singularity in infinite derivative gravity
Alexey S. Koshelev, João Marto, Anupam Mazumdar
In this paper, we will show that the equations of motion of the quadratic in curvature, ghost free, infinite derivative theory of gravity will not permit an anisotropic collapse of…
Schwarzschild -singularity is not permissible in ghost free quadratic curvature infinite derivative gravity
Alexey S. Koshelev, João Marto, Anupam Mazumdar
In this paper we will study the complete equations of motion for a ghost free quadratic curvature infinite derivative gravity. We will argue that within the scale of non-locality,…
