Fermionic Isocurvature Perturbations

Daniel J. H. Chung, Hojin Yoo, Peng Zhou

Isocurvature perturbations in the inflationary literature typically involve quantum fluctuations of bosonic field degrees of freedom. In this work, we consider isocurvature perturb…

Quadratic Isocurvature Cross-Correlation, Ward Identity, and Dark Matter

Daniel J. H. Chung, Hojin Yoo, Peng Zhou

Sources of isocurvature perturbations and large non-Gaussianities include field degrees of freedom whose vacuum expectation values are smaller than the expansion rate of inflation.…
