Pair production of scalars around near-extremal Kerr-Sen black holes
Abstract We investigate the charged scalar pair production near the horizon of a near-extremal Kerr-Sen black holes. The condition for pair production to occur has relation to the violation of Breitenlohner–Freedman bound in an $$\hbox {AdS}_2$$ AdS2 space. The method employed in this work has been...
