Noise-induced escape from a metastable state of a dynamical system is studied close to a saddle-node bifurcation point, but in the region where the system remains underdamped. The activation energy of escape scales as a power of the distance to the bifurcation point. We find two types of scaling and the corresponding critical exponents.
Method for finding mechanism and activation energy of magnetic transitions, applied to skyrmion and antivortex annihilation
Scaling and crossovers in activated escape near a bifurcation point
Activated escape of periodically modulated systems
