dc.description.abstractThe formation of a naked singularity in f(R) global monopole spacetime is considered in view of quantum mechanics. Quantum test elds obeying the Klein-Gordon, Dirac and Maxwell equations are used to probe the classical timelike naked singularity developed at r = 0. We prove that the spatial derivative operator of the elds fails to be essentially self-adjoint. As a result, the classical timelike naked singularity formed in f(R) global monopole spacetime remains quantum mechanically singular when it is probed with quantum elds having di erent spin structures. Pitelli and Letelier (Phys. Rev. D 80, 104035, 2009) had shown that for quantum scalar (spin 0) probes the general relativistic global monopole singularity remains intact. For speci c modes electromagnetic (spin 1) and Dirac eld (spin 1=2) probes, however, we show that the global monopole spacetime behaves quantum mechanically regular. The admissibility of this singularity is also incorporated within the Gubser's singularity conjecture.en_US
