Holographic energy density in the Brans-Dicke teory
Hungsoo Kim, H. W. Lee, Y. S. Myung
We study cosmological applications of the holographic energy density. Considering the holographic energy density as a dynamical cosmological constant, we need the Brans-Dicke theor…
Noncommutative spacetime effect on the slow-roll period of inflation
Hungsoo Kim, Gil Sang Lee, Yun Soo Myung
We study how the noncommutative spacetime affects on inflation. First we obtain the noncommutative power spectrum of the curvature perturbations produced during inflation in the sl…
Second-order corrections to noncommutative spacetime inflation
Hungsoo Kim, Gil Sang Lee, Hyung Won Lee +1
We investigate how the uncertainty of noncommutative spacetime affects on inflation. For this purpose, the noncommutative parameter is taken to be a zeroth order slow-roll pa…
Single 3-Brane Brane-World in Six Dimension
D. K. Park, Hungsoo Kim
The single 3-brane brane world at six dimension is examined when the extra dimensions are not compact. Although the warp factor diverges at the asymptotic region of the extra dimen…
Singular Quantum Mechanical Viewpoint of Localized Gravity in Brane-World Scenario
D. K. Park, Hungsoo Kim
The graviton localized on the 3-brane is examined in Randall-Sundrum brane-world scenario from the viewpoint of one-dimensional singular quantum mechanics. For the Randall-Sundrum…
Nonvanishing Cosmological Constant of Flat Universe in Brane-World Scenario
D. K. Park, Hungsoo Kim, S. Tamaryan
The finite temperature effect is examined in Randall-Sundrum brane-world scenario with inclusion of the matter fields on the brane. At zero temperature it is found that the theory…
