First law of thermodynamics and Friedmann equations of Friedmann-Robertson-Walker universe
TL;DR: In this paper, the first law of thermodynamics is applied to the apparent horizon of a Friedmann-Robertson-Walker universe and assuming the geometric entropy given by a quarter of the horizon area, the Friedmann equations describing the dynamics of the universe with any spatial curvature are derived.

Journal ArticleDOI
P-V criticality in the extended phase space of Gauss-Bonnet black holes in AdS space
TL;DR: In this paper, the authors studied the P −V criticality and phase transition in the extended phase space of charged Gauss-Bonnet black holes in anti-de Sitter space, where the cosmological constant appears as a dynamical pressure of the system and its conjugate quantity is the thermodynamic volume of the black holes.
Journal ArticleDOI
Hessence: a new view of quintom dark energy
TL;DR: In this article, a non-canonical complex scalar field is proposed as the dark energy to avoid the difficulty of the Q-ball formation which gives trouble to the spintessence model.
Journal ArticleDOI
Cosmology with interaction between phantom dark energy and dark matter and the coincidence problem
TL;DR: In this article, a cosmological model in which phantom dark energy is coupled to dark matter by phenomenologically introducing a coupled term to the equations of motion of dark energy and dark matter was studied.
