Abstract

In this short paper, we study Majorana fermions in terms of a modified Chandrasekhar's separation for the Dirac equation in Kerr-Newman-type spacetimes. If the electric charge or magnetic charge is nonzero, we show that nontrivial differentiable time-periodic Majorana fermions do not exist outside the event horizon in Kerr-Newman and Kerr-Newman-AdS spacetimes, and between the event horizon and the cosmological horizon in Kerr-Newman-dS spacetime., Comment: 8 pages
