Stationary dark energy with a baryon-dominated era: solving the coincidence problem with a linear coupling
We show that all cosmological models with an accelerated stationary global attractor reduce asymptotically to a dark energy field with an exponential potential coupled linearly to a perfect fluid dark matter. In such models the abundance of the dark components reaches a stationary value and therefor...
