Kostas Skenderis: Holographic cosmology and cosmological observations
I will provide an introduction to holographic cosmology, outlining how this new framework addresses long standing issues in cosmology, like the origin of the arrow of time and the resolution of the Big Bang singularity. I will then present holographic models describing a non-geometric very early universe and discuss how they their predictions compare with CMB data and discuss possible observational signatures of the resolution of the Big Bang singularity.
Edward Wilson-Ewing: Loop quantum cosmology
I will give an introduction to loop quantum cosmology, first explaining the main ideas underlying the theory, then briefly describing the quantum theory, and showing how the initial big-bang singularity is replaced by a bounce. I will also discuss cosmological perturbation theory in loop quantum cosmology, and point out some possible observational signatures from loop quantum cosmology for inflation, and for other cosmological scenarios.
