WMAP 7 year constraints on CPT violation from large angle CMB anisotropies
CMBR theory CMBR experiments
2011/10/18
We constrain the rotation angle $\alpha$ of the linear polarization of CMB photons using the large angular scale (up to $\sim 4^\circ$) signal in WMAP 7 year data. At these scales, the CMB polarizatio...
Limit on Lorentz and CPT violation of the bound Neutron Using a Free Precession 3He/129Xe co-magnetometer
Lorentz CPT violation of the bound Neutron Free Precession 3He/129Xe co-magnetometer
2010/12/20
We report on the search for Lorentz violating sidereal variations of the frequency difference of colocated spin-species while the Earth and hence the laboratory reference frame rotates with respect to...
Remarks on Lorentz and CPT Violation in Field Theory
Lorentz and CPT violation Chern-Simons-like Finite temperature
2010/9/29
In this brief review we explicitly calculate the radiative corrections to the Chern-Simons-like term in the cases of zero and finite temperature, and in the gravity theory. Our results are obtained un...
