A larger value for by an evolving gravitational constant

Matteo Braglia, Mario Ballardini, William T. Emond +4

We provide further evidence that a massless cosmological scalar field with a non-minimal coupling to the Ricci curvature of the type alleviates…

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…

The nonperturbative decay of SUSY flat directions

A. E. Gumrukcuoglu, Keith A. Olive, Marco Peloso +1

We compute the nonperturbative decay of supersymmetric flat directions due to their D-term potential. Flat directions can develop large vacuum expectation values (vevs) during infl…
