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.…

Isocurvature Constraints and Gravitational Ward Identity
Hojin Yoo
Axions and WIMPZILLAs are well-motivated dark matter candidates with interesting cos- mological implications, such as isocurvature perturbations and non-Gaussianities. How- ever, t…
