Integrable Kerr Black Hole Spectrum from Twistor Symmetries

Alfredo Guevara Gonzalez

*,*Harvard University*,*Note: Special time

When the Kerr metric is endowed with a NUT charge of value $N=\pm iM$, the original two isometries of the spacetime are promoted to seven phase space symmetries. We show that these extra hidden symmetries arise naturally from its twistor space description, as a consequence of the spacetime being self-dual. The corresponding wave equation becomes integrable and equivalent to the Hydrogen atom spectrum. The original Kerr metric with $N=0$ can be realized as an exactÂ deformation, thus leading to a correction of the spectrum analogous to the Zeeman effect.

The talk is in 469 Lauritsen.
