A worldsheet for Kerr
We show that the Newman-Janis shift property of the exact Kerr solution can be interpreted in terms of a worldsheet effective action. This holds both in gravity, and for the single-copy Kerr‾‾‾‾√ solution in electrodynamics. At the level of equations of motion, we show that the Newman-Janis shift ho...
