Low-frequency scattering calculations show scalar probes through the MMP wormhole are mostly reflected or trapped at early times with late leakage to half the black-hole cross-section, while charged massless fermions transmit with unit probability via a Callan-Rubakov-like channel.

abstract
Working in the context of spontaneously broken gauge theories, we show that the magnetically charged Reissner-Nordstrom solution develops a classical instability if the horizon is sufficiently small. This instability has significant implications for the evolution of a magnetically charged black hole. In particular, it leads to the possibility that such a hole could evaporate completely, leaving in its place a nonsingular magnetic monopole.

Branch I of non-Abelian black holes with quartic self-interactions is linearly stable for all regular parameter values of the coupling χ.
Generalized GHS-GM black hole with dilaton and monopole shows thermal stability increasing as scalar charge decreases and QNMs damping as black hole charge increases.

How traversable is a traversable wormhole?
