Violating Electrodynamics and Chern-Simons Modified Gravity
Mingzhe Li, Yi-Fu Cai, Xiulian Wang +1
The electrodynamics with a Chern-Simons term violates Lorentz and symmetries with a non-vanishing . For a fixed vector , in this paper we…

Cosmic Ray Positrons from Cosmic Strings
Robert Brandenberger, Yi-Fu Cai, Wei Xue +1
We study the spectrum of cosmic ray positrons produced by a scaling distribution of non-superconducting cosmic strings. In this scenario, the positrons are produced from the jets w…

DBI-Curvaton
Sheng Li, Yi-Fu Cai, Yun-Song Piao
In this paper, we study a curvaton model described by a Dirac-Born-Infeld-like action. We calculate the spectrum of curvature perturbation induced by DBI-curvaton and estimate its…
