主　　题：dark matter matter bounce fermi bounce baryogenesis 

摘      要：We elaborate on a toy model of matter bounce, in which the matter content is constituted by two fermion species endowed with four fermion interaction terms. We describe the curvaton mechanism that is thus generated, and then argue that one of the two fermionic species may realize baryogenesis, while the other（lighter） one is compatible with constraints on extra hot dark matter particles.
