The effects on CMB power spectra and bispectra from the polarization rotation and its correlations with temperature and E-polarization
Hua Zhai, Si-Yu Li, Mingzhe Li +2
The Chern-Simons term, through which the cosmic Axion-like field couples to the electromagnetic field, has the effect to rotate CMB polarization directions and to break the CPT sym…
Joint constraint on primordial gravitational waves and polarization rotation angle with current CMB polarization data
Hua Zhai, Si-Yu Li, Mingzhe Li +1
Cosmological CPT violation will rotate the polarized direction of CMB photons, convert partial CMB E mode into B mode and vice versa. It will generate non-zero EB, TB spectra and c…
Probing Primordial Gravitational Waves: Ali CMB Polarization Telescope
Hong Li, Si-Yu Li, Yang Liu +14
In this paper, we will give a general introduction to the project of Ali CMB Polarization Telescope (AliCPT), which is a Sino-US joint project led by the Institute of High Energy P…
On Dark Energy Isocurvature Perturbation
Jie Liu, Mingzhe Li, Xinmin Zhang
Determining the equation of state of dark energy with astronomical observations is crucially important to understand the nature of dark energy. In performing a likelihood analysis…
