Theoretical Physics of the Early Universe

Prof. Björn Garbrecht

Research Field

The observed Universe can be very well described in terms of the Standard Model (SM) of Particle Physics, gravitation, neutrinos and Cold Dark Matter. The present understanding ranges from times below the Electroweak Phase transition, 10^-12 seconds after the Bang, until today, 13.8 billion years later. The cosmic evolution depends sensitively on initial conditions, such as the matter-antimatter asymmetry, the Dark Matter abundance and density perturbations, that eventually grow into galaxies.

Understanding the initial conditions is one of the key motivations for exploring Physics beyond the SM. Cosmology thus complements laboratory experiments such as the Large Hadron Collider. The particular research interests of our group encompass the origin of the matter-antimatter asymmetry and of density perturbations from inflation. In particular, we develop theoretical methods for calculations on the dynamics and reactions of elementary particles at very high temperatures and in curved spacetimes, i.e. under conditions present in the Early Universe.
