Fermion excitations of a tense brane black hole
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. © 2008 The American Physical Society.
