Closed and broken electromagnetic orbits in Kerr--Newman spacetime
Erasmo Caponio, Giulio Sanzeni, Stefan Suhr
We study future-pointing timelike solutions of the Lorentz force equation in the sub-extremal Kerr--Newman spacetime, with special attention to the time-machine region $\mathfrak T…
Geodesic causality in Kerr spacetimes with
Giulio Sanzeni, Karim Mosani
The analytic extension of the Kerr spacetimes into the negative radial region contains closed causal curves for any non-zero rotation parameter and mass parameter . Furtherm…
Nonexistence of closed timelike geodesics in Kerr spacetimes
Giulio Sanzeni
The Kerr-star spacetime is the extension over the horizons and in the negative radial region of the Kerr spacetime. Despite the presence of closed timelike curves below the inner h…
Non existence of closed and bounded null geodesics in Kerr spacetimes
Giulio Sanzeni
The Kerr-star spacetime is the extension over the horizons and in the negative radial region of the slowly rotating Kerr black hole. It is known that below the inner horizon, there…
