      abstract     = {The onset of rapid slip along initially quiescent
                      frictional interfaces, the process of “earthquake
                      nucleation,” and dissipative spatiotemporal slippage
                      dynamics play important roles in a broad range of physical
                      systems. Here we first show that interfaces described by
                      generic friction laws feature stress-dependent steady-state
                      slip pulse solutions, which are unstable in the quasi-1D
                      approximation of thin elastic bodies. We propose that such
                      unstable slip pulses of linear size L∗ and characteristic
                      amplitude are “critical nuclei” for rapid slip in a
                      nonequilibrium analogy to equilibrium first-order phase
                      transitions and quantitatively support this idea by
                      dynamical calculations. We then perform 2D numerical
                      calculations that indicate that the nucleation length L∗
                      exists also in 2D and that the existence of a fracture
                      mechanics Griffith-like length LG<L∗ gives rise to a
                      richer phase diagram that features also sustained slip
                      pulses.},
