Metric-Affine Formalism of Higher Derivative Scalar Fields in Cosmology
Mingzhe Li, Xiulian Wang
Higher derivative scalar field theories have received considerable attention for the potentially explanations of the initial state of the universe or the current cosmic acceleratio…
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…
Spacetime variation of and the CMB power spectra after the recombination
Xiulian Wang, Mingzhe Li
The possible variation of the fine structure constant may be due to the non-minimal coupling of the electromagnetic field to a light scalar field which can be the candidate of dark…
Testing CPT Symmetry with CMB Measurements
Jun-Qing Xia, Hong Li, Xiulian Wang +1
In this paper we study the possibility of testing \emph{CPT} symmetry with Cosmic Microwave Background (CMB) measurements. Working with an effective lagrangian of the photon with \…
Reconstructing large running-index inflaton potentials
Chiyi Chen, Bo Feng, Xiulian Wang +1
Recent fits of cosmological parameters by the first year Wilkinson Microwave Anisotropy Probe (WMAP) measurement seem to favor a primordial scalar spectrum with a large varying ind…
Dark Energy Constraints from the Cosmic Age and Supernova
Bo Feng, Xiulian Wang, Xinmin Zhang
Using the low limit of cosmic ages from globular cluster and the white dwarfs: Gyr, together with recent new high redshift supernova observations from the HST/GOODS progr…
