Quantum Reduced Loop Gravity

By Emanuele Alesci and Francesco Cianfrani


Quantum Reduced Loop Gravity provides a promising framework for a consistent characterization of the early Universe dynamics. Inspired by BKL conjecture, a flat Universe is described as a collection of Bianchi I homogeneous patches. The resulting quantum dynamics is described by the scalar constraint operator, whose matrix elements can be analytically computed. The effective semiclassical dynamics is discussed, and the differences with Loop Quantum Cosmology are emphasized.Comment: 6 pages, proceedings of Frontiers of Fundamental Physics 14 - FFP14, 15-18 July 2014, Marseille, accepted for publication in Proceedings of Scienc
