Dynamics of coupled phantom and tachyon fields
M. Shahalam, S. D. Pathak, Shiyuan Li +2
In this paper, we apply the dynamical analysis to a coupled phantom field with scaling potential taking particular forms of the coupling (linear and combination of linear), and pre…
Thermodynamics of interacting tachyonic scalar field
S. D. Pathak, M. M. Verma, Shiyuan Li
In this paper we discuss the laws of thermodynamics for interacting tachyonic scalar field. The components of the tachyonic scalar field in the universe are taken to exist in the s…
Nonsingular Bouncing Model in Closed and Open universe
Manabendra Sharma
We investigate the cosmology of a class of model with noncanonical scalar field and matter both in FRW closed and open background. Writing the Einstein Equations in terms of dimens…
Combination of e+/e- ratio from AMS-02 and gamma ray line from Fermi-LAT with implication for Dark Matter
Shiyuan Li, Yonggang Luo
The precise AMS-02 data provide definite information for the e+/e- ratio in 100 - 350 GeV region. Assuming that the recent gamma ray line observed by Fermi-LAT experiment is produc…
