Ashtekar formulation of general relativity and loop space nonperturbative quantum gravity: A Report
Classical and Quantum Gravity, 1991The formulation of general relativity discovered by Ashtekar (1986, 1987) and the recent results obtained in non-perturbative quantum gravity using loop-space techniques are reviewed. The new formulation is based on the choice of a set of Lagrangian (and Hamiltonian) variables, instead of the spacetime metric.

Black holes in effective loop quantum gravity: Covariant holonomy modifications
Physical Review DEmergent modified gravity provides a covariant, effective framework for obtaining spherically symmetric black hole solutions in models of loop quantum gravity with scale-dependent holonomy modifications.

The Hamiltonian constraint remains an elusive object in loop quantum gravity because its action on spinnetworks leads to changes in their corresponding graphs.

ONE-LOOP QUANTUM GRAVITY ON DE SITTER SPACE
International Journal of Modern Physics A, 1993We demonstrate that being formulated properly all the approaches to de Sitter quantum gravity give the same one-loop path integral as was obtained by Taylor and Veneziano in a framework of the gauge fixed procedure.

We investigate the physical interpretation of the loop states of non-perturbative quantum general relativity in the regime of graviton physics, namely the regime of first order excitations around the Poincare-invariant vacuum. We construct the general form of the loop state functionals invariant under the linearized constraints.

Plane Gravitational Waves and Flat Space in Loop Quantum Gravity
2014Classically a system of arbitrary plane gravitational waves propagating in the same or opposite directions can be restricted by first-class constraints to unidirectional waves, which travel without dispersion on a flat background. The unidirectionality constraints are formulated as well-defined Loop Quantum Gravity operators, together with criteria for
