Gravitational Baryogenesis in Rainbow Gauss-Bonnet gravity
P. Goodarzi, H. Mohseni Sadjadi, R. Darabi
The gravitational baryogenesis is studied in regularized four dimensional Einstein Gauss Bonnet model with rainbow gravity corrections. This combined framework generates a non vani…
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 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…
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…
Testing Modified Teleparallel Gravity by Neutrino Oscillations
H. Yazdani Ahmadabadi, H. Mohseni Sadjadi
In the framework of modified teleparallel gravity, we study neutrino flavor conversion. We show how the presence of spacetime torsion modifies both neutrino flavor oscillation and…
