Quantum noises and the large scale structure
Wo-Lung Lee
We propose that cosmological density perturbation may originate from passive fluctuations of the inflaton, which are induced by colored quantum noise due to the coupling of the inf…

Running spectral index and mode-mode correlation of inflationary perturbations from off-equilibrium effects
Da-Shin Lee, Li-Zhi Fang, Wolung Lee +1
We study the off-equilibrium effects of inflaton on the dynamics of primordial perturbations in the O(N) model. A self-consistent off-equilibrium formalism is employed to investiga…
