Four-Dimensonal Gauss-Bonnet Gravity Without Gauss-Bonnet Coupling to Matter - Spherically Symmetric Solutions, Domain Walls and Spacetime Singularities
Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva
We discuss a new extended gravity model in ordinary spacetime dimensions, where an additional term in the action involving Gauss-Bonnet topological density is included withou…
Gauss-Bonnet Gravity in Without Gauss-Bonnet Coupling to Matter - Cosmological Implications
Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva
We propose a new model of Gauss-Bonnet gravity. To avoid the usual property of the integral over the standard Gauss-Bonnet scalar becoming a total derivative term, we e…
Confinement/Deconfinement and Gravity-Assisted Emergent Higgs Mechanism in Quintessential Cosmological Model
Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva
Motivated by the ideas of Jacob Bekenstein concerning gravity-assisted symmetry breaking, we consider a non-canonical model of f(R)=R+R^2 extended gravity coupled to neutral scalar…
Quintessence, Unified Dark Energy and Dark Matter, and Confinement/Deconfinement Mechanism
Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva
We describe a new type of generalized gravity-matter models where gravity couples in a non-conventional way to a scalar "inflaton" field, to a second scalar "darkon" f…
