The SFB 676 has been funded by the DFG from 2006 to 2018. The project was completed with a special colloquium in June 2018. A book with the scientific results of the SFB 676 has been published in September 2018.

J. Haller and M. Grefe (eds.), “Particles, Strings and the Early Universe: The Structure of Matter and Space-Time,” Hamburg (2018), DOI: 10.3204/PUBDB-2018-00782.

Many research directions developed within the SFB 676 will be continued within the Cluster of Excellence "Quantum Universe" starting 1 January 2019.

C10 – Cosmological implications of first order phase transitions

Project Leaders

Thomas Konstandin (e-mail | group homepage)

Günter Sigl (e-mail | group homepage)


The project is concerned with phenomena at the interface between particle physics and cosmology. In particular, we are interested in phenomena where the link between these two fields is established by a first-order phase transition. A first-order phase transition can lead to several cosmological relics as for example a baryon asymmetry, sizable gravitational waves or primordial magnetic fields. Ultimately, the analysis of these phenomena can yield valuable information on how the electroweak symmetry was broken during the evolution of the Universe.
