260028 VO Field Theory Methods in Cosmology and Astroparticle Physics

Dr. Josef Pradler, WS2017/2018, Uni Wien

Aims, contents and method of the course

The lecture aims at discussing topics that are connected with important phenomena in cosmology and/or astroparticle physics, but are rarely covered in Quantum Field Theory and Relativity courses.

Cosmology: action principle, energy-momentum tensor, gauge transformations and perturbation theory in General Relativity; Einstein and Friedmann equations and standard cosmological history; scalar fields in a gravitational background, inflation and inflationary perturbations; tensor modes*, gravitational particle production*;

Astroparticle physics: particle dispersion and decay in media, plasmon decay and stellar energy loss; vacuum stability*, axions*, effective theory of dark matter direct detection**time permitting; some topics may still change

Plan of the course:

I.  From Einstein's Equations to Cosmology

Lecture Notes, Exercises

II. Standard Cosmology & Shortcomings

Lecture Notes, Exercises I, Exercises II

III. Inhomogeneous Universe & Origin of Structure
