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…

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…

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…

A Tachyon Field around the Black Hole

Narges Rashidi

We study the effects of the presence of the tachyon field around the black hole. We show that in presence of the tachyon field, unlike the ordinary canonical scalar field, the time…

Inflation in Energy-Momentum Squared Gravity in Light of Planck2018

Marzieh Faraji, Narges Rashidi, Kourosh Nozari

We study cosmological dynamics of the energy-momentum squared gravity. By adding the squared of the matter field's energy-momentum tensor () to the Einstein Hil…

Lowering the self-coupling of the scalar field in a generalized Higgs inflation

Kourosh Nozari, S. Shafizadeh, N. Rashidi

We study cosmological dynamics of a generalized Higgs inflation. By expanding the action up to the second and third order in the small perturbations, we study the primordial pertur…
