Dark energy, dissipation, and the coincidence problem

In a recent paper we showed that a quintessence scalar field plus a dissipative matter fluid can drive late cosmic accelerated expansion and simultaneously solve the coincidence problem. In this Brief Report we extend this result to the cases when the scalar field is replaced either by a Chaplygin g...
