New constraints on cosmic polarization rotation from the ACTPol cosmic microwave background B-Mode polarization observation and the BICEP2 constraint update
Hsien-Hao Mei, Wei-Tou Ni, Wei-Ping Pan +2
Recently ACTPol has measured the cosmic microwave background (CMB) B-mode and E-mode polarizations and obtained TE, EE, BB, TB and EB power spectra in the multipole range 225-8725.…
Foundations of Classical Electrodynamics, Equivalence Principle and Cosmic Interactions: A Short Exposition and an Update
Wei-Tou Ni, Hsien-Hao Mei, Shan-Jyun Wu
We look at the foundations of electromagnetism in this 1st LeCosPA Symposium. For doing this, after some review (constraints on photon mass etc.), we use two approaches. The first…
Pseudoscalar-photon Interactions, Axions, Non-Minimal Extensions, and Their Empirical Constraints from Observations
Wei-Tou Ni, A. B. Balakin, Hsien-Hao Mei
Pseudoscalar-photon interactions were proposed in the study of the relations among equivalence principles. The interaction of pseudoscalar axion with gluons was proposed as a way t…
Axion Search with Q & A Experiment
Hsien-Hao Mei, Wei-Tou Ni, Sheng-Jui Chen +1
Dark matter is a focused issue in galactic evolution and cosmology. Axion is a viable particle candidate for dark matter. Its interaction with photon is an effective way to detect…
The status and prospects of the Q & A experiment with some applications
Hsien-Hao Mei, Wei-Tou Ni, Sheng-Jui Chen +1
Motivated to measure the QED birefringence and to detect pseudoscalar-photon interaction, we started to build up the Q & A experiment (QED [Quantum Electrodynamics] and Axion exper…
Measurement of the Cotton-Mouton effect in nitrogen, oxygen, carbon dioxide, argon, and krypton with the Q & A apparatus
Hsien-Hao Mei, Wei-Tou Ni, Sheng-Jui Chen +1
Experiments for vacuum birefringence and vacuum dichroism have been set up with high-finesse high magnetic experimental apparatuses, which seem to be ideal for small gaseous Cotton…
