Inflation of the universe by the non-minimal y (R) F 2 models

Autor: Özcan Sert

The cosmological solutions of the non-minimal $ Y (R)F^2 $ theory which are compatible with FRW space-time are investigated. In order to avoid the isotropy violation of a vector field, it can be considered that the presence of a triplet of vector fie

O presente trabalho é um retorno à discussão dos acoplamentos diretos da gravitação com o tensor de Faraday. A nossa abordagem consiste em investigá-los não enquanto correção à propagação local de fótons, ainda que possa servir a tal pro

International audience; We study a large family of metric-affine theories with a projective symmetry, including non-minimally coupled matter fields which respect this invariance. The symmetry is straightforwardly realised by imposing that the connect

Holographic superconductors with the general RF2-type couplings

Autor: Sert, Özcan

We explore the effects of the general non-minimally coupled $RF^2$-type couplings on the holographic s-wave superconductors numerically in the Schwarzschild-AdS background. We calculate the condensation and conductivity of the model for the coupling

RF2 formunda çiftlenimli holografik süperiletkenler

Autor: Taner, Emre

Bu tez çalışmasında diferansiyel formların dış cebirini kullanarak gravitasyon teorilerini inceliyoruz. Öncelikle gerekli olan temel kavramları verdikten sonra Einstein Gravitasyon teorisini differansiyel formaları kullanarak ifade ediyoruz
