Journal ArticleDOI
Entanglement entropy in a holographic p-wave superconductor model
TL;DR: In this paper, the authors investigated the behavior of the entanglement entropy of dual field theory in a holographic p-wave model and observed the second order, first order and zeroth order phase transitions.
Journal ArticleDOI
Cosmological scaling solutions and cross-coupling exponential potential
TL;DR: In this paper, a phase-space analysis of cosmology containing multiple scalar fields with a positive or negative cross-coupling exponential potential is presented, and it is shown that there exist power-law kinetic-potential scaling solutions for a sufficiently flat positive potential or for a steep negative potential.
Journal ArticleDOI
An alternative explanation of the conflict between 1/R gravity and solar system tests
TL;DR: In this paper, it was argued that the 1 / R gravity conflicts with solar system tests and that this difficulty might be avoided if one treats the 1/R term as a correction to the scalar curvature term in the high curvature limit R ≫ μ 2.
Journal ArticleDOI
Holography in a radiation-dominated universe with a positive cosmological constant
Rong-Gen Cai,Yun Soo Myung +1 more
TL;DR: In this paper, a cosmological D bound on the entropy of matter in the universe was introduced, and the Friedmann equation was shown to coincide with the Cardy-Verlinde formula.
Journal ArticleDOI
Quasinormal modes in the background of charged Kaluza-Klein black hole with squashed horizons
TL;DR: In this article, the scalar perturbation in the background of the charged Kaluza-Klein black holes with squashed horizons is studied and the position of infinite discontinuities of the heat capacities can be reflected in quasinormal spectrum.
