Abstract

In this talk I review a recently proposed modulation of the power spectrum of primordial density fluctuations generated through transplankian (maybe stringy) effects during inflation. I briefly discuss the mechanism leading to the modulation, apply it to a generic slow-roll scenario of inflation and argue that the effects obtained are rather generic signatures of transplanckian physics. I also investigate how these primordial modulation effects may leave an imprint in the cosmic microwave background radiation, possibly detectable by satellite experiments.
