Testing the Lorentz and CPT Symmetry with CMB polarizations and a non-relativistic Maxwell Theory
Yi-Fu Cai, Mingzhe Li, Xinmin Zhang
We present a model for a system involving a photon gauge field and a scalar field at quantum criticality in the frame of a Lifthitz-type non-relativistic Maxwell theory. We will sh…
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…
Cosmological CPT Violation, Baryon/Leptogenesis and CMB Polarization
Mingzhe Li, Jun-Qing Xia, Hong Li +1
In this paper we study the cosmological CPT-violation and its implications in baryo/leptogenesis and CMB polarization. We propose specifically a variant of the models of gravitatio…
A Single Scalar Field Model of Dark Energy with Equation of State Crossing -1
Mingzhe Li, Bo Feng, Xinmin Zhang
In this paper we study the possibility of building models of dark energy with equation of state across -1 and propose explicitly a model with a single scalar field which gives rise…
Gravitational Leptogenesis and Its Signatures in CMB
Bo Feng, Hong Li, Mingzhe Li +1
We study the phenomenologies in astrophysics and particularly in CMB associated with the gravitational leptogenesis. Our results show that future CMB polarization experiments, such…
Gravitational Leptogenesis and Neutrino Mass Limit
Hong Li, Mingzhe Li, Xinmin Zhang
Recently Davoudiasl {\it et al} \cite{steinhardt} have introduced a new type of interaction between the Ricci scalar and the baryon current , and propo…
