I shall present a new baryogenesis scenario based on coherent production and mixing of different fermionic species. The mechanism is operative during phase transitions, at which the fermions acquire masses via Yukawa couplings to scalar fields. Baryon production is efficient when the mass matrix is nonadiabatically varying, nonsymmetric and when it violates CP and B-L simultaneously. To be concrete, I will show how coherent baryogenesis works in a hybrid inflationary scenario embedded in a supersymmetric Pati-Salam GUT.
