| 520 | _ | _ | |a In loop quantum gravity (LQG), quantum states of the gravitational field are represented by labelled graphs called spinnetworks. Their dynamics can be described by a Hamiltonian constraint, which modifies the spinnetwork graphs. Fixed graph approximations of the dynamics have been extensively studied, but its full graph-changing action so far remains elusive. The latter, alongside the solutions of its constraint, are arguably the missing features to access physically correct quantum-relativistic phenomenology from canonical LQG. Here, we introduce the first numerical tool that implements graph-changing dynamics via the Hamiltonian constraint. We find new solutions to this constraint and show that some quantum-geometrical observables behave differently than in the graph-preserving truncation. This work aims at fostering a new era of numerical simulations in canonical LQG that, crucially, embrace the graph-changing aspects of its dynamics, laying aside debated approximations. |
