Superradiant Phenomena for Spinor Fields in Rotating Black Hole Geometry

Superradiant Phenomena for Spinor Fields in Rotating Black Hole Geometry

We derive the results (i) the ortho-normal and completeness relations for normal modes and (ii) non-existence of zero mode for spinor fields in rotating black hole geometry. From these results, we show that superradiant phenomena for spinor fields should be type 2: positive momentum on the horizon (...
