A minimal Length Uncertainty Approach to Cosmological Constant Problem
Abdel Magied Diab, Abdel Nasser Tawfik
Based on quantum mechanical framework for the minimal length uncertainty, we demonstrate that the generalized uncertainty principle (GUP) parameter could be best constrained by rec…
Consequences of Minimal Length Discretization on Line Element, Metric Tensor and Geodesic Equation
Abdel Nasser Tawfik, Abdel Magied Diab, Sameh Shenawy +1
When minimal length uncertainty emerging from generalized uncertainty principle (GUP) is thoughtfully implemented, it is of great interest to consider its impacts on {\it "gravitat…
Minimal-supersymmetric extended inflation field in Horava-Lifshitz gravity
A. Tawfik, A. Diab, E. Abou El Dahab
We study the Friedmann inflation in general covariant Horava-Lifshitz (HL) gravity without the projectability conditions and with detailed and non-detailed balance conditions. Acco…
Perturbative instability of inflationary cosmology from quantum potentials
Abdel Nasser Tawfik, Abdel Magied Diab, Eiman Abou El Dahab
It was argued that the Raychaudhuri equation with a quantum correction term seems to avoid the Big Bang singularity and to characterize an everlasting Universe [PLB741,276(2015)].…
Perturbative Instability of Cosmology from Quantum Potential
Abdel Nasser Tawfik, Abdel Magied Diab, Eiman Abou El Dahab +1
Apart from its debatable correctness, we examine the perturbative stability of the recently proposed cosmology from quantum potential. We find that the proposed quantum corrections…
Friedmann inflation in Horava-Lifshitz gravity with a scalar field
Abdel Nasser Tawfik, Abdel Magied Diab, Eiman Abou El Dahab
We study Friedmann inflation in general Horava-Lifshitz (HL) gravity with detailed and non-detailed but also without the projectability conditions. Accordingly, we derive the modif…
