Fermion excitations of a tense brane black hole

Understand

By finding the spinor eigenvalues for a single deficit angle (d-2)-sphere, we derive the radial potential for fermions on a d-dimensional black hole background that is embedded on a codimension two brane with conical singularity, where the deficit angle is related to the brane tension.

• From this we obtain the quasi-normal mode spectrum for bulk fermions on such a background.
• As a byproduct of our method, this also gives a rigorous proof for integer spin fields on the deficit 2-sphere.
