Cosmological constraints from Gauss-Bonnet braneworld with large-field potentials
Kyong Hee Kim, Yun Soo Myung
We calculate the spectral index and tensor-to-scalar ratio for patch inflation defined by and , using the slow-roll expansion. The patch…
Cosmological parameters in the noncommutative inflation
Yun Soo Myung
We investigate how the uncertainty of noncommutative spacetime could explain the WMAP data. For this purpose, the spectrum is divided into the IR and UV region. We introduce a nonc…
Test of patch cosmology with WMAP
Kyong Hee Kim, Yun Soo Myung
We calculate the power spectrum, spectral index, and running spectral index for inflationary patch cosmology arisen from Gauss-Bonnet braneworld scenario using the Mukhanov equatio…
Second-order corrections to slow-roll inflation in the brane cosmology
Kyung Hee Kim, Hyung Won Lee, Yun Soo Myung
We calculate the power spectrum, spectral index, and running spectral index for the RS-II brane inflation in the high-energy regime using the slow-roll expansion. There exist sever…
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…
