Primordial perturbations from inflation
David Wands
I review the standard analysis of adiabatic scalar and tensor perturbations produced by slow-roll inflation driven by a single scalar field, before going on to discuss recent work…

Density Perturbations from Two-field Inflation
David Wands, Juan Garcia-Bellido
We discuss metric perturbations produced during a period of inflation in the early universe where two scalar fields evolve. The final scalar perturbation spectrum can be calculated…
