Quantum corrections to slow-roll inflation: scalar and tensor modes
Andersen, Jens Oluf; Eriksson, Magdalena Britt; Tranberg, Anders (Peer reviewed; Journal article, 2021)Inflation is often described through the dynamics of a scalar field, slow-rolling in a suitable potential. Ultimately, this inflaton must be identified with the expectation value of a quantum field, evolving in a quantum ... -
Stochastic inflation from quantum field theory and the parametric dependence of the effective noise amplitude
Andersen, Jens Oluf; Tranberg, Anders; Eriksson, Magdalena Britt (Peer reviewed; Journal article, 2022-02)The non-linear dynamics of long-wavelength cosmological fluctuations may be phrased in terms of an effective classical, but stochastic evolution equation. The stochastic noise represents short-wavelength modes that continually ...
