Cosmological Co-evolution of Yang-Mills Fields and Perfect Fluids (2005)
Barrow, John D., Jin, Yoshida, Maeda, Kei-ichi
We study the co-evolution of Yang-Mills fields and perfect fluids in Bianchi type I universes. We investigate numerically the evolution of the universe and the Yang-Mills fields during the radiation...
Chaos of Yang-Mills Field in Class A Bianchi Spacetimes (2004)
Studying Yang-Mills field and gravitational field in class A Bianchi spacetimes, we find that chaotic behavior appears in the late phase (the asymptotic future). In this phase, the Yang-Mills field...
Chaotic dynamics in preheating after inflation (2004)
Jin, Yoshida, Tsujikawa, Shinji
We study chaotic dynamics in preheating after inflation in which an inflaton $\phi$ is coupled to another scalar field $\chi$ through an interaction $(1/2)g^2\phi^2\chi^2$. We first estimate the size...
