Query: Hidden Supersymmetry in Dirac Fermion Quasinormal Modes of Black Holes   We connect the quasinormal modes corresponding to Dirac fermions in various
black holes backgrounds to an N=2 supersymmetric quantum mechanics algebra,
which can be constructed from the radial part of the fermionic solutions of the
Dirac equation. In the massless fermion case, the quasinormal modes are in
bijective correspondence with the zero modes of the fermionic system and this
results to unbroken supersymmetry. The massive case is more evolved but as we
prove, supersymmetry remains unbroken even in this case.
