Static Spherically Symmetric Solutions in Modified Entropic Gravity
A. Rostami, M. Rostampour, A. Yarahmadi +1
Within the entropic gravity paradigm introduced by Verlinde, one assumes that the microscopic degrees of freedom residing on the holographic screen obey the equipartition law of en…
Gravitational Bound State Perturbations Inside Black Holes and Isospectrality
Hassan Firouzjahi, Kazem Rezazadeh, Masoud Molaei
We study the bound state solutions for the polar perturbations in the interior of the Schwarzschild black hole. It is shown that for a given value of the spherical harmonic index $…
Relativistic MOND Theory from Modified Entropic Gravity
A. Rostami, K. Rezazadeh, M. Rostampour
We derive a relativistic extension of Modified Newtonian Dynamics (MOND) within the framework of entropic gravity by introducing temperature-dependent corrections to the equipartit…
A Dark Matter Model with Quadratic Equation of State: Background Evolution and Structure Formation
Kazem Rezazadeh, Ebrahim Yusofi, Alireza Talebian
We propose that dark matter (DM) possesses a quadratic equation of state, which becomes significant at high densities, altering the Universe's evolution during its early stages. We…
Cosmological Implications of Modified Entropic Gravity
Kazem Rezazadeh
Taking into account the temperature corrections of the energy equipartition law for the bits of information that are coarse-grained on the holographic screen leads to a modificatio…
Cosmological perturbation theory with trinity of scalar fields
Amjad Ashoorioon, Shinji Mukohyama, Kazem Rezazadeh +1
We present an explicit formulation of cosmological perturbation theory for three-field models with a flat field space. By performing rotations to align one field with the direction…
Spherical Collapse Approach for Non-standard Dark Matter Models and Enhanced Early Galaxy Formation in JWST
Zahra Davari, Amjad Ashoorioon, Kazem Rezazadeh
Using the spherical collapse approach, we investigate the impact of two alternative dark matter models, each characterized by distinct non-zero equations of state, one constant and…
Cascading Dark Energy
K. Rezazadeh, A. Ashoorioon, D. Grin
The standard cosmological model is in the midst of a stress test, thanks to the tension between supernovae-based measurements of the Hubble constant and inferences of its v…
