- Inflationary cosmological perturbations of quantum-mechanical origin
- Constraints on Inflation from Planck & BICEP2
inflationary scenario is currently considered to be the most promising
paradigm to describe the origin of the perturbations in the early
universe. It corresponds to a period of accelerated expansion before
the hot Big Bang phase. Inflation is typically achieved using scalar
fields, and it is the quantum fluctuations associated with the scalar
fields that are responsible for the creation of the primordial
perturbations. The perturbations generated during inflation leave their
signatures as anisotropies in the Cosmic Microwave Background (CMB).
With the CMB anisotropies being measured to greater and greater
precision, we are presently in an unprecedented situation of being able
to arrive at strong constraints on the physics of the early universe.
In these two hours lectures, I first review the theory of inflationary
perturbations and then, using the results obtained in the first
lecture, I describe the implications of the recently released Planck
& BICEP2 data for inflation
