Small dark energy and stable vacuum from Dilaton–Gauss–Bonnet coupling in TMT
/ Guendelman, Eduardo I. ; Nishino, Hitoshi ; Rajpoot, Subhash
In two measures theories (TMT), in addition to the Riemannian measure of integration, being the square root of the determinant of the metric, we introduce a metricindependent density Φ in four dimensions defined in terms of scalars φa by Φ=εμνρσεabcd(∂μφa)(∂νφb)(∂ρφc)(∂σφd) . [...]

Twomeasure approach to breaking scaleinvariance in a standardmodel extension
/ Guendelman, Eduardo I. ; Nishino, Hitoshi ; Rajpoot, Subhash
We introduce Weyl's scaleinvariance as an additional global symmetry in the standard model of electroweak interactions. [...]

Unified dark energy and dust dark matter dual to quadratic purely kinetic Kessence
/ Guendelman, Eduardo ; Nissimov, Emil ; Pacheva, Svetlana
We consider a modified gravity plus single scalarfield model, where the scalar Lagrangian couples symmetrically both to the standard Riemannian volumeform (spacetime integration measure density) given by the square root of the determinant of the Riemannian metric, as well as to another nonRiemannian volumeform in terms of an auxiliary maximalrank antisymmetric tensor gauge field.

Dark energy and dark matter from hidden symmetry of gravity model with a nonRiemannian volume form
/ Guendelman, Eduardo ; Nissimov, Emil ; Pacheva, Svetlana
We show that dark energy and dark matter can be described simultaneously by ordinary Einstein gravity interacting with a single scalar field provided the scalar field Lagrangian couples in a symmetric fashion to two different spacetime volume forms (covariant integration measure densities) on the spacetime manifold – one standard Riemannian given by g (square root of the determinant of the pertinent Riemannian metric) and another nonRiemannian volume form independent of the Riemannian metric, defined in terms of an auxiliary antisymmetric tensor gauge field of maximal rank.

Scalar gauge fields
/ Guendelman, Eduardo ; Singleton, Douglas
In this paper we give a variation of the gauge procedure which employs a scalar gauge field, B ( x ), in addition to the usual vector gauge field, A μ ( x ). [...]

Scale symmetry breaking from total derivative densities and the cosmological constant problem
/ Guendelman, Eduardo I. ; Nishino, Hitoshi ; Rajpoot, Subhash
The use in the action integral of totally divergent densities in generally coordinate invariant theories can lead to interesting mechanisms of spontaneous symmetry breaking of scale invariance. [...]
