CHARGED PARTICLE INTERFEROMETRY IN PLEBAŃSKI–DEMIAŃSKI BLACK HOLE SPACE-TIMES

The Plebański–Demiański space-time is a general axially symmetric space-time of Petrov type D characterized by seven parameters related to mass, rotation, cosmological constant, NUT parameter, electric and magnetic charges, and acceleration.¹ This space-time of generalized black hole solutions has as limiting cases the Schwarzschild, Reissner-Nordström, Kerr-Newman or Kerr-NUT-de Sitter space-times. We describe a matter wave interferometry with charged particles in this space–time. We show that it is possible to have access to all parameters separately except the acceleration. For neutral particles only a combination of electric and magnetic charge is accessible.
