      abstract     = {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.},
