Time evolution of semiclassical states in the one-vertex model of quantum-reduced loop gravity
Ilkka Mäkinen
We compute numerically the time evolution of simple semiclassical states describing homogeneous and isotropic spatial geometries in quantum-reduced loop gravity under a deparametri…

On the covariant formulation of gauge theories with boundaries
Mehdi Assanioussi, Jerzy Kowalski-Glikman, Ilkka Mäkinen +1
In the present article, we review the classical covariant formulation of Yang-Mills theory and general relativity in the presence of spacetime boundaries, focusing mainly on the de…

Master constraint approach to quantum-reduced loop gravity
Ilkka Mäkinen
We introduce a master constraint operator on the kinematical Hilbert space of loop quantum gravity representing a set of gauge conditions which classically fix the densitized triad…
