Cosmological Evolution of a Quintom Model of Dark Energy
Zong-Kuan Guo, Yun-Song Piao, Xinmin Zhang +1
We investigate in this paper the cosmological evolution of a dark energy model with two scalar fields where one of the scalar has canonical kinetic energy and another scalar has ne…

Cosmological Scaling Solutions and Cross-coupling Exponential Potential
Zong-Kuan Guo, Yun-Song Piao, Rong-Gen Cai +1
We present a phase-space analysis of cosmology containing multiple scalar fields with a positive or negative cross-coupling exponential potential. We show that there exist power-la…
