Cosmological First-Order Vacuum Phase Transitions in an Expanding Anisotropic Universe
A. Savaş Arapoğlu, A. Emrah Yükselci
We examine the anisotropy originated from a first-order vacuum phase transitions through three-dimensional numerical simulations. We apply Bianchi Type-I metric to our model that h…
Formalizing Slow-roll Inflation in Scalar-Tensor Theories of Gravitation
Kemal Akın, A. Savaş Arapoğlu, A. Emrah Yükselci
The viability of slow-roll approximation is examined by considering the structure of phase spaces in scalar-tensor theories of gravitation and the analysis is exemplified with a no…
Effect of the spatial curvature of the Universe on the form of the gravitational potential
Maxim Eingorn, A. Emrah Yukselci, Alexander Zhuk
Within the cosmic screening approach, we obtain the exact formulas for the velocity-independent gravitational potentials produced by matter in the form of discrete sources distribu…
Neutron Star Structure in the Presence of Nonminimally Coupled Scalar Fields
A. Savaş Arapoğlu, K. Yavuz Ekşi, A. Emrah Yükselci
We study the structure of neutron stars in scalar-tensor theories for the nonminimal coupling of the form . We solve the hydrostatic equilibrium equations for tw…
