报告摘要：We review inflation and matter bounce cosmology as paradigms for the early universe, and show how these can explain the observed features of cosmic microwave background radiation. I then show instantiations of these two frameworks that are achieved in term of auxiliary scalar fields, which nevertheless have no correspondence in particle physics, and mention theories exploiting gauge fields, which stand as very few exceptions to the main-stream models of scalar-fields. I then focus on the applications of spinor fields to the frameworks of matter-bounce and inflation, and review how the physics that fermion fields encodes can actually provide a viable paths towards CMBR physics, and a richer framework to be used to interpret data.
