The Generalized Second Law in Dark Energy Dominated Universes |
Abstract _ |
The generalized second law of gravitational thermodynamics is examined in scenarios where the dark energy dominates the expansion. For quintessence and phantom fields this law is fulfilled but it may fail when the dark energy is represented by a Chaplygin gas. However, if a black hole is allowed in the picture, the law can be violated if the field is of phantom type. |
