The prospect of a stochastic gravitational wave (GW) background from the primordial universe offers a promising new window for cosmology and fundamental physics.
Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.
For our latest developments/activities in this area, please see the listing below.

The Domain Wall (DW) problem is the fact that DW networks that result from the spontaneous breaking of discrete symmetries tend to dominate the universe's energy budget.
However, if the symmetry is not exact the network annihilates and the problem turns into a virtue, as the network tends to be an abundant component before its collapse, and is thus easier to probe.
