A Generally Covariant Model of Spacetime as a 4-Brane in 4+1 Flat Dimensions
Mert Ergen, Metin Arık
We construct a simple toy model of a closed FLRW spacetime by starting from a flat five dimensional scalar field space. The action contains no curvature terms. A string-like potent…
An analytical model of depth-dose distributions for carbon-ion beams
Fulya Halıcılar, Metin Arık
Improving effective treatment plans in carbon ion therapy, especially for targeting radioresistant tumors located in deep seated regions while sparing normal tissues, depends on a…
The Exterior Calculus of Quadratic Gravity
Metin Arık, Ahmet Baykal, Tekin Dereli +1
The metric tensor field equations for the general quadratic curvature gravity in four spacetime dimensions are derived by making use of the algebra of the exterior forms defined on…
Higgs mode of modified cosmology
Metin Arik, Tarik Tok
We consider a model where the Standard Model is added to the Einstein Lagrangian together with a Jordan-Brans-Dicke(JBD) coupling. The time-dependent Higgs field has an important r…
