Coupled dark energy and dark matter from dilatation anomaly
Cosmological runaway solutions may exhibit an exact dilatation symmetry in the asymptotic limit of infinite time. In this limit, the massless dilaton or cosmon could be accompanied by another massless scalar field - the bolon. At finite time, small time-dependent masses for both the cosmon and the b...
