Gravitational Baryogenesis in Rainbow Gauss-Bonnet gravity
P. Goodarzi, H. Mohseni Sadjadi, R. Darabi
The paper investigates how combining rainbow gravity with a four‑dimensional Einstein–Gauss–Bonnet model can generate a non‑zero time derivative of the Ricci scalar during the radi…
Spontaneous scalarization around a black hole in a dark matter halo
M. Navid Gasemi Zad, H. Mohseni Sadjadi
We demonstrate that in a scalar-tensor theory where dark matter is conformally coupled to a scalar field, a black hole surrounded by a Hernquist dark matter halo can undergo sponta…
Mass-Varying Dark Matter Induced Scalarization and Scalar Clouds around Black Holes
H. Mohseni Sadjadi, M. Navid Gasemi Zad
We consider a black hole solution embedded in a mass varying dark matter (DM) halo and study scalarization induced by DM. We derive the required conditions on the scalar DM couplin…
Mass Varying Neutrino Oscillation in Teleparallel Gravity
H. Mohseni Sadjadi, H. Yazdani Ahmadabadi
In the Cartan teleparallel formulation of gravity, a scalar field coupled to the torsion tensor can acquire an environment dependent effective mass. This gives rise to a screening…
Constraints on Gravity from Solar Neutrino Conversion
H. Yazdani Ahmadabadi, H. Mohseni Sadjadi
We report new constraints on the parameters of teleparallel gravity, derived from its imprints on neutrino flavor oscillations. Our analysis reveals that the presence of spa…
Mass Varying Neutrino Oscillation in Scalar-Gauss-Bonnet Gravity
H. Mohseni Sadjadi, H. Yazdani Ahmadabadi
We investigate how matter density affects neutrino oscillations by considering a mass-varying neutrino scenario where the neutrino mass depends on a scalar field. This scalar field…
