Title: Structure Formation with Two Periods of Inflation: Beyond plain LCDM

 

Abstract: We discuss structure formation in models with a spectator field

in small-field inflation which accommodate a secondary period

of inflation.  In such models, subgalactic scale primordial

fluctuations can be much suppressed in comparison to the usual

power-law LCDM model while the large scale fluctuations remain

consistent with current observations. We discuss how a secondary

inflationary epoch may give rise to observable features in the small

scale power spectrum and hence be tested by the structures in the

Local Universe.
