1. A naturally regularized path integral formalism / Nozari, Kourosh ; Hajebrahimi, M. ; Khodadi, M. ; Etemadi, A.
A minimal uncertainty in position measurement comes into play if, for instance, one incorporates gravitational interaction of photon and electron in the Heisenberg’s Electron Microscope Gedanken Experiment. [...]

3. On the viability of Planck scale cosmology with quartessence / Khodadi, Mohsen ; Nozari, Kourosh ; Hajkarim, Fazlollah
Growing evidence as the observations of the CMB (cosmic microwave background), galaxy clustering and high-redshift supernovae address a stable dynamically universe dominated by the dark components. [...]

4. Planck scale effects on the stochastic gravitational wave background generated from cosmological hadronization transition: A qualitative study / Khodadi, Mohsen ; Nozari, Kourosh ; Abedi, Habib ; Capozziello, Salvatore
We reconsider the stochastic gravitational wave background spectrum produced during the first order hadronization process, in presence of ultraviolet cutoffs suggested by the generalized uncertainty principle as a promising signature towards the Planck scale physics. [...]

6. Some astrophysical aspects of a Schwarzschild geometry equipped with a minimal measurable length / Khodadi, Mohsen ; Nozari, Kourosh ; Hajizadeh, Anahita
By considering a deformation of the Schwarzschild metric in the presence of a minimal measurable length which still respects the equivalence principle, we study corrections to the standard general relativistic predictions for some astrophysical phenomena such as stability of circular orbits of black hole accretion disks, redshift of black hole accretion disks, gravitational tidal forces and the geodetic drift rate.
