Eternal Inflation: Prohibited by Quantum Gravity?
Yi Wang
We investigate how eternal inflation is affected by quantum gravity effects. We consider general features of quantum gravity, such as renormalizability, complementarity, minimal le…
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…
