Colloquium by Yi Wang (HKUST)

Expansion History of the Primordial Universe

Abstract: 

We first briefly review the hot big bang cosmology and its horizon problem. Afterwards we introduce the early universe scenarios, namely, inflation, matter bounce, string gas and ekpyrosis. To distinguish those scenarios from observation (i.e. measure the evolution history of the primordial universe), two methods are introduced: primordial gravitational waves and quantum primordial standard clocks.
