Loop Quantum Gravity Vacuum with Nondegenerate Geometry

Symmetry, Integrability and Geometry: Methods and Applications, 2012
In loop quantum gravity, states of the gravitational field turn out to be excitations over a vacuum state that is sharply peaked on a degenerate spatial geometry.

Testing loop quantum cosmology

Comptes Rendus. Physique, 2017
Loop quantum cosmology predicts that quantum gravity effects resolve the big-bang singularity and replace it by a cosmic bounce. Furthermore, loop quantum cosmology can also modify the form of primordial cosmological perturbations, for example by reducing power at large scales in inflationary models or by suppressing the tensor-to-scalar ratio in the ...

Efficiently evaluating loop integrals in the EFTofLSS using QFT integrals with massive propagators

Journal of High Energy Physics
We develop a new way to analytically calculate loop integrals in the Effective Field Theory of Large Scale-Structure. Previous available methods show severe limitations beyond the one-loop power spectrum due to analytical challenges and computational and
