Journal ArticleDOI
Interacting vectorlike dark energy, the first and second cosmological coincidence problems
TL;DR: In this paper, the cosmological evolution of the vector-like dark energy interacting with background perfect fluid is investigated, and it is shown that the first and second cosmologically coincident problems can be alleviated at the same time in this scenario.
Journal ArticleDOI
Phase transition and thermodynamical geometry of Reissner-Nordström-AdS black holes in extended phase space
TL;DR: In this article, the authors study the thermodynamics and thermodynamic geometry of a Reissner-Nordstr\"om-AdS black hole in the extended phase space by treating the cosmological constant as being related to the number of colors in the boundary gauge theory and its conjugate quantity as the associated chemical potential.
Journal ArticleDOI
Statefinder diagnostic and w–w′ analysis for the agegraphic dark energy models without and with interaction
Hao Wei,Rong-Gen Cai +1 more
TL;DR: In this paper, the authors investigated the age-graphic dark energy models without and with interaction by means of statefinder diagnostic and w − w w "analysis" and showed that the state-finder diagnostic can be used to analyze the dark energy model with and without interaction.
Journal ArticleDOI
Thermodynamic curvature of the BTZ black hole
Rong-Gen Cai,Jin-Ho Cho +1 more
TL;DR: In this article, the authors apply the concept of thermodynamic geometry to the BTZ black hole and find that the thermodynamic curvature diverges at the extremal limit of the black hole, which means that extremal black hole is the critical point with the temperature zero.
Journal ArticleDOI
Horizon thermodynamics and gravitational field equations in Horava-Lifshitz gravity
TL;DR: In this paper, the relationship between the first law of thermodynamics and the gravitational field equation at a static, spherically symmetric black hole horizon in Horava-Lifshitz theory with/without detailed balance was explored.
