Loop quantum cosmology is considered in inflation era. A slow roll scalar field solution with power law potential is presented in the neighborhood of transition time, i.e. when the universe enters inflation phase from super-inflation. The compatibility of the model with Planck 2013 data is discussed. The domain of validity of second and the generalized second laws of thermodynamics for this solution and some other examples is studied.

An Extended Second Law of Thermodynamics

The paper postulates that the second law should read sign(T)dS ≥ 0, permitting entropy decrease for negative-temperature systems, and illustrates it with LQC and Onsager vortices.
