Role of matter in gravitation: going beyond the Einstein-Maxwell theory
A. Emir Gumrukcuoglu, Ryo Namba
For field theories in curved spacetime, defining how matter gravitates is part of the theory building process. In this letter, we adopt Bekenstein's multiple geometries approach to…
On the viability of bigravity cosmology
Michael Kenna-Allison, A. Emir Gumrukcuoglu, Kazuya Koyama
We revisit the question of viability of bigravity cosmology as a candidate for dark energy. In the context of the low energy limit model, where matter couples to a single metric, w…
Stable cosmology in ghost-free quasidilaton theory
A. Emir Gumrukcuoglu, Kazuya Koyama, Shinji Mukohyama
We present a novel cosmological solution in the framework of extended quasidilaton theory which underwent scrutiny recently. We only consider terms that do not generate the Boulwar…
New Quasidilaton theory in Partially Constrained Vielbein Formalism
Antonio De Felice, A. Emir Gümrükçüoğlu, Lavinia Heisenberg +2
In this work we study the partially constrained vielbein formulation of the new quasidilaton theory of massive gravity which couples to both physical and fiducial metrics simultane…
Gravitational Field Equations on and off a 3-Brane World
A. N. Aliev, A. E. Gumrukcuoglu
The effective gravitational field equations on and off a 3-brane world possessing a Z_{2} mirror symmetry and embedded in a five-dimensional bulk spacetime with cosmological consta…
