    • The isocurvature density fluctuation at Hubble-radius crossing is δρ/ρ∼Hi/φi∼Hi/f, where Hi is the Hubble parameter during inflation and φi∼f is the initial value of the field. Constraints from the microwave background anisotropy on the amplitude of adiabatic perturbations in inflation require Hi≲1013 GeV, so the isocurvature amplitude is acceptable if f≳1018 GeV.
