Inflationary NonGaussianity from Thermal Fluctuations
Bin Chen, Yi Wang, Wei Xue
We calculate the contribution of the fluctuations with the thermal origin to the inflationary nonGaussianity. We find that even a small component of radiation can lead to a large n…
String Gas Cosmology and Non-Gaussianities
Bin Chen, Yi Wang, Wei Xue +1
Recently it has been shown that string gas cosmology, an alternative model of the very early universe which does not involve a period of cosmological inflation, can give rise to an…
Hawking-Moss Tunneling in Noncommutative Eternal Inflation
Yi-Fu Cai, Yi Wang
The quantum behavior of noncommutative eternal inflation is quite different from the usual knowledge. Unlike the usual eternal inflation, the quantum fluctuation of noncommutative…
Generalized Space-time Noncommutative Inflation
Wei Xue, Bin Chen, Yi Wang
We study the noncommutative inflation with a time-dependent noncommutativity between space and time. From the numerical analysis of power law inflation, there are clues that the CM…
