Observational Viability of -Superpotential Inflation with GUP-Induced Corrections
Narges Rashidi, Maryam Roushan
We study a -superpotential inflationary model within a GUP-inspired quantum-gravity framework. Using horizon thermodynamics, we review the GUP-corrected Friedmann equations…
Anisotropic Dirac-Born-Infeld Inflation with Non-Vacuum Initial States: Primordial Perturbations, Non-Gaussianity, and Observational Constraints
Narges Rashidi, Maryam Roushan
We investigate linear and nonlinear primordial perturbations in an anisotropic Dirac-Born-Infeld (DBI) inflationary model with a non-vacuum initial state. Using the Arnowitt-Deser-…
Cosmological Implications of the Extended Uncertainty Principle: Energy Conditions, Stability, and Late Time Acceleration
Maryam Roushan, Narges Rashidi
We study the cosmological consequences of the Extended Uncertainty Principle (EUP) by deriving modified Friedmann equations through thermodynamic arguments. The evolution of the ef…
Observational Viability of Anisotropic Inflation Revisited
Maryam Roushan, Narges Rashidi, Kourosh Nozari
We investigate anisotropic inflation within the single-field model featuring an intermediate scale factor. Our analysis reveals that the anisotropic nature of the Friedmann equatio…
Traces of Quantum Gravity Effects at Late time Cosmological Dynamics via Distance Measures
Maryam Roushan, Narges Rashidi, Kourosh Nozari
Inspired by the entropy-area relation of black hole thermodynamics, we study the thermodynamics of cosmological apparent horizon in a spatially flat Friedmann-Robertson-Walker (FRW…
Quantum Gravity Effects on the Tachyon Inflation from Thermodynamic Perspective
M. Bitaj, N. Rashidi, K. Nozari +1
By considering the Friedmann equations emerging from the entropy-area law of black hole thermodynamics in the context of the generalized uncertainty principle, we study tachyon inf…
Observational Viability of the Intermediate DBI Inflation in the Presence of a Minimal Length
Narges Rashidi, Maryam Roushan, Kourosh Nozari
We consider an intermediate Dirac-Born-Infeld (DBI) inflationary model in the presence of a minimal measurable length in the theory. We show that, the presence of a minimal measura…
Visible Energy Alternative to Dark Energy
Maryam Roushan, Narges Rashidi, Kourosh Nozari
Quantum gravitational effects usually are assumed to be important on small scale (Planck scale), but actually these effects are also very significant on large (cosmological) scales…
Thermostatistics with an Invariant Infrared Cutoff
M. Roushan, K. Nozari
Quantum gravitational effects may affect the large scale dynamics of the universe. Phenomenologically, quantum gravitational effect at large distances can be encoded in an extended…
