Loop quantum gravity and observations
A. Barrau, J. Grain
Quantum gravity has long been thought to be completely decoupled from experiments or observations. Although it is true that smoking guns are still missing, there are now serious ho…
The performance of the bolometer array and readout system during the 2012/2013 flight of the E and B experiment (EBEX)
Kevin MacDermid, Asad M. Aboobaker, Peter Ade +38
EBEX is a balloon-borne telescope designed to measure the polarization of the cosmic microwave background radiation. During its eleven day science flight in the Austral Summer of 2…
Loop Quantum Cosmology with Complex Ashtekar Variables
Jibril Ben Achour, Julien Grain, Karim Noui
We construct and study Loop Quantum Cosmology (LQC) when the Barbero-Immirzi parameter takes the complex value . We refer to this new quantum cosmology as complex Loop Qua…
Detecting chiral gravity with the pure pseudospectrum reconstruction of the cosmic microwave background polarized anisotropies
A. Ferte, J. Grain
We consider the possible detection of parity violation at the linear level in gravity using polarized anisotropies of the cosmic microwave background. Since such a parity violation…
Anomaly-free cosmological perturbations in effective canonical quantum gravity
Aurelien Barrau, Martin Bojowald, Gianluca Calcagni +2
This article lays out a complete framework for an effective theory of cosmological perturbations with corrections from canonical quantum gravity. Since several examples exist for q…
