Thawing and Freezing Quintessence Models: A thermodynamic Consideration
arXiv:1906.10408 · doi:10.1140/epjc/s10052-019-7406-z
Abstract
Thawing and freezing quintessence models are compared thermodynamically. Both of them are found to disobey the Generalized Second Law of Thermodynamics. However, for freezing models, there is still a scope as this breakdown occurs in the past, deep inside the radiation dominated era, when a standard scalar field model with a pressureless matter is not a correct description of the matter content. The thawing model has a pathological breakdown in terms of thermodynamics in a finite future.
