    Title: Thermal excitation of the universe and the second law of thermodynamics
    Abstract:
    The stochastic inflation describes the thermal fluctuation of a homogeneous
    scalar field in a de Sitter patch. The scalar field could transient from the bottom to the
    top of an effective potential with a finite probability due to its thermal dissipation.
    However, its horizon entropy that is proportional to the inverse of the square of Hubble
    parameter would decrease during the transition, which apparently looks like the second
    law of thermodynamics was broken. I will show that taking into account the entropy production
    due to the cosmological decoherence leads to the consistent picture of the thermal excitation
    of the universe where the second law of thermodynamics can be satisfied.
